A 334 mL sample of hydrogen was collected over water at 23C on day when the atmospheric pressure was 756 mm Hg.The vapor pressure of water under these conditions is 17.54 mm Hg. What volume, in liters, will the dry hydrogen ( No water vapor) occupy at STP?
Answer:
0.299 L
Explanation:
We'll begin by calculating the pressure of dry gas. This can be obtained as follow:
Measured pressure = 756 mm Hg
Water vapor pressure = 17.54 mm Hg
Pressure of dry gas =?
Pressure of dry gas = (Measured pressure) – (Water vapor pressure)
Pressure of dry gas = 738.46 mmHg
Finally, we shall determine the volume occupied at STP. This can be obtained as follow:
Initial volume (V₁) = 334 mL = 334 / 1000 = 0.334 L
Initial pressure (P₁) = 738.46 mmHg
Initial temperature (T₁) = 23 °C = 23 °C + 273 = 296 K
Final pressure (P₂) = 760 mmHg
Final temperature (T₂) = 273 K
Final volume (V₂)
P₁V₁/T₁ = P₂V₂/T₂
738.46 × 0.334 / 296 = 760 × V₂/273
Cross multiply
296 × 760 × V₂ = 738.46 × 0.334 × 273
224960 × V₂ = 67334.2597
Divide both side by 224960
V₂ = 67334.2597 / 224960
V₂ = 0.299 L
Thus, the volume of the dry gas st STP is 0.299 L.

Stu Dent wants to create a salt water solution. He uses 0.614 moles of salt and 182 milliliters of water. What is the molarity of the solution?
Type your answer...
Answer: The molarity of solution is 3.37 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]
where,
n = moles of solute = 0.614
[tex]V_s[/tex] = volume of solution in ml = 182 ml
Now put all the given values in the formula of molarity, we get
[tex]Molarity=\frac{0.614\times 1000}{182}=3.37M[/tex]
Therefore, the molarity of solution is 3.37 M
16.1 g of bromine are mixed with 8.42 g of chlorine to give an actual
yield of 21.1 g of bromine monochloride.
The question is complete, the complete question is;
16.1g of bromine are mixed with 8.42g of chlorite to give an actual yield of 21.1g of bromine monochloride.
Answer:
91 %
Explanation:
Br2 + Cl2 ------>2BrCl
Number of moles of Chlorine = 8.42/71 = 0.119 moles
If 1 mole of Cl2 yields 2 moles of BrCl
0.119 moles of Cl2 will yield 0.119 moles * 2/1 = 0.238 moles of BrCl
Number of moles of Br2 reacted = 16.1/160 = 0.1 moles
If 1 mole of Br2 yielded 2 moles of BrCl
0.1 moles of Br2 yields 0.1 * 2/1 = 0.2 moles of BrCl
Bromine is the limiting reactant.
Mass of BrCl produced = 0.2 moles * 115.357 g/mol = 23.07 g
Theoretical yield = 23.07 g
Actual yield = 21.1 g
Percentage yield = Actual yield/Theoretical yield * 100
= 21.1/23.07 * 100 = 91 %

Explanation:
Sea water contains 2% salt (NaCl) by weight. Given that water has a
density of 1g/mL. Determine the concentration of salt in:
(a) mg/L , (b) ppm.
Answer:
a) Concentration of salt in mg/L = 2g/100mL
b) concentration in ppm = 20000 ppm
Explanation:
Percentage composition of salt by weight in water = 2%
Density of water = 1 g/mL
100 mL of water will has a mass of 100 g
Mass of salt in 100 g of water = 2% ×100 g = 2 g
Therefore, 2 g of salt is dissolved in 100 mL of solution
Concentration of salt in 100 mL of solution = 2g/100mL
a) Concentration in mg/L
Mass of salt = 2 g = 2000 mg
Volume of solution = 100 mL = 0.1 L
Concentration in mg/L = 2000 mg/0.1 L
Concentration in mg/L = 20000 mg/L
b) Concentration in ppm
1 ppm = 1mg/L
Therefore, concentration in ppm = 20000 ppm
Which of the following best defines base isolation?(1 point)
Base isolation is a technique used by engineers to help prevent damage to buildings by volcanoes. The main structure of the building is separate from the base, which allows lava to pass under the building without causing much damage.
Base isolation is a technique used to prevent large-scale damage from volcanoes. New communities being built are set as far back as possible from the base of a volcano.
Base isolation is a technique used to prevent damage to buildings during tsunamis. The main structure of the building is separate from the base, which allows water to pass beneath buildings without causing much damage.
Base isolation is a technique used by engineers to help prevent damage to buildings by earthquakes. The main structure of the building is separate from the base and sits on a bed of springs.
Base isolation is a technique used by engineers to help prevent damage to buildings by earthquakes. The main structure of the building is separate from the base and sits on a bed of springs.
What is base isolation?Base isolation is a technique developed to prevent or minimise damage to buildings during an earthquake.
A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure). By separating the structure from its base the amount of energy that is transferred to the superstructure during an earthquake is reduced significantly.
Hence, option D is correct.

Obtain a 50-mL volumetric flask. 3. Use a pipet to add the appropriate volume of stock solution to the flask. 2. Add approximately 10 mL of deionized water to the empty flask.
Answer:
The steps in order are;
1. Obtain a 50-mL volumetric flask
2. Add approximately 10 mL of deionized water to the empty flask
3. Use a pipet to add the appropriate volume of stock solution to the flask
4. Cap the flask and invert several times to mix
5. Fill the volumetric flask with deionized water until the meniscus touches the mark
6. Swirl the flask to mix the contents
The volume of the acetic acid to be added to the solution is 15 mL
Explanation:
The given steps are;
4. Cap the flask and invert several times to mix
5. Fill the volumetric flask with deionized water until the meniscus touches the mark
6. Swirl the flask to mix the contents
1. Obtain a 50-mL volumetric flask
3. Use a pipet to add the appropriate volume of stock solution to the flask
2. Add approximately 10 mL of deionized water to the empty flask
The given parameters are;
The volume of the volumetric flask = 50-mL
The concentration of the final solution of acetic acid = 0.6 mg/L
The concentration of the stock solution = 2.0 mg/L
Let 'x' represent the volume of the stock solution added, we have;
2.0 mg/L·x + (50 - x)×0 = 0.6 mg/L × 50-mL
x = 0.6 mg/L × 50-mL/(2.0 mg/L) = 15 mL
The volume of the stock solution to be added, x = 15 mL
