Explanation:
119 kPa x 1 atm/101 kPa = 1.18 atm
2) Convert temperature to Kelvin
35 + 273 = 308 K
3) Use PV=nRT and solve for V
(1.18 atm)(V)=(0.0972 mol)(0.0821)(308 K)
V = (0.0972 mol)(0.0821)(308 K) / (1.18 atm)
V = 2.08 L

How many moles of I2 are in 8.23 moles of NaI ?
Answers
Answer: 4.12
Explanation:
we know that the given mol is 8.23 mol and they are 2NaI and I2 so we will write the equation like this.
8.23mol NaI x 1mol of I2 ÷ 2molNaI = 4.115≅ 4.12 mol of I2
we placed NaI at the bottom to cancel out with the 8.23 mol of NaI

#carryONlearning1. If you have 5g of pennies how many dozen pennies do you have?
Answers
Answer:
15.69 dozen
Explanation:
Mass of penny = 5 g
Dozens of penny =..?
Next, we shall convert 5 g to gross. This can be obtained as follow:
3824 g = 1000 gross
Therefore,
5 g = 5 g × 1000 gross / 3824 g
5 g = 1.3075 gross
Thus, 5 g is equivalent to 1.3075 gross.
Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:
1 gross = 12 dozen
Therefore,
1.3075 gross = 1.3075 gross × 12 dozen / 1 gross
1.3075 gross = 15.69 dozen
Thus, 5 g of penny is equivalent to 15.69 dozen
What is the primary difference between a molecule and a compound?
A. All molecules are compounds, but not all compounds are molecules
B. Molecules always contain only one type of atom, unlike compounds
C. Compounds must be composed of more than one type of atom
Answers
Answer:
A. "All molecules are compounds, but not all compounds are molecules"
Explanation:
An example of a compound-molecule is oxygen. The elemenal is O, because the periodic table isn't describing molecules, it's describing atoms. The molecule is O2 because it takes 2 O atoms to make a molecule of oxygen.
The primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom'.
Explanation:
A molecule is a group of atoms of the same or different types of atoms bound to each other.Molecules are the smallest unit of a substance that possesses the characteristic of the substance.A compound is a substance in which two or more different types of atoms are bound to each other.In compounds, atoms of different elements are in a fixed proportion.So, from this, we can conclude that the primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom'.

2. Hydrocarbons consist of carbon and hydrogen. 5.7 g of a hydrocarbon contains 4.8 g of carbon.
If the relative molecular mass of the hydrocarbon is 114, determine its molecular formula.
Answers
Answer:
The molecular formula of the hydrocarbon compound is C₈H₁₈
Explanation:
The type of chemical substance in the question = Hydrocarbon
The mass of the hydrocarbon = 5.7 g
The mass of carbon in the given hydrocarbon (sample) = 4.8 g
The relative molecular mas of the hydrocarbon = 114 g
Therefore, the mass of hydrogen in the sample, H = 5.7 g - 4.8 g = 0.9 g
The ratio of the mass of carbon in the sample = 4.8/5.7
The ratio of the mass of hydrogen in the sample = 0.9/5.7
By the law of constant composition, we have;
The mass of carbon in a mole of the hydrocarbon = (4.8/5.7) × 114 g = 96 g
The molar mass of carbon, C = 12 g/mol
The number of moles of carbon in a mole of the hydrocarbon, 'n₁', is given as follows;
n₁ = 96 g/12 g = 8 moles
The mass of hydrogen in a mole of the hydrocarbon = (0.9/5.7) × 114 g = 18 g
The molar mass of hydrogen, H ≈ 1 g/mol
The number of moles of hydrogen in a mole of the hydrocarbon, 'n₂', is given as follows;
n₂ = 48 g/1 g = 18 moles
Therefore, in each each molecule of the compound, we have have 8 atoms of carbon, 'C', and 18 atoms of hydrogen, 'H'
Therefore, we get;
The molecular formula of the hydrocarbon compound is C₈H₁₈ which is the chemical formula for the hydrocarbon also known as octane

79.05 M mL = 1.50 M
79.05 M mL / 1.50 M = x
52.7 mL = x
59.7 mL needs to be added to the original 15.00 mL solution in order to dilute it from 6.77 M to 1.50 M.

When 10 grams of water completely evaporate into water vapor, the volume of the water vapor is greater than the volume of the original liquid water, but the mass remains the same. Why does the mass stay the same? Which answer is correct?
A
The temperature of the liquid water and water vapor is the same.
The temperature of the liquid water and water vapor is the same.
B
The density of the liquid water is the same as the density of the water vapor.
The density of the liquid water is the same as the density of the water vapor.
C
The number of atoms in the water vapor is equal to the number of atoms in the liquid water.
The number of atoms in the water vapor is equal to the number of atoms in the liquid water.
D
The distance between the water molecules is the same in the liquid and the vapor.
The distance between the water molecules is the same in the liquid and the vapor.
Answers
Answer: I think the answer is B or C, its kind of hard.
As the number of atoms in the water vapor is equal to the number of atoms in the liquid water. Therefore, the mass of the water remains the same.
What is evaporation?Evaporation is a process that usually happens on the surface of water or liquid and it involves the conversion of the liquid phase into the gaseous phase. This process involves a change in the state of matter of water or liquids.
When the water is completely evaporated into water vapor the density of the water vapor is less than the density of the liquid water as the vapors occupy a large volume in comparison to liquid water.
But the number of atoms in the water vapor is the same as the number of atoms in the liquid water. The mass of the water is due to the mass of the atoms.
Therefore, the mass of the water remains the same during the phase transition from liquid water to water vapors. Therefore, option (C) is correct.
