A 16.4 g sample of calcium chloride is dissolved in enough water to make 750.0 mL of solution. Calculate the molarity of calcium chloride in this solution. plz help!!!
The molarity is an important method to calculate the concentration of a solution. The molarity of calcium chloride of 16.4 g in 750.0 mL of solution is 0.196 mol L⁻¹.
What is molarity?The molarity of a solution is defined as the number of moles of the solute present per litre of the solution. It is mainly employed in calculating the molarity of a binary solution. It is represented as 'M' and unit is mol L⁻¹.
The equation used to calculate the molarity is given as:
Molarity = Number of moles of the solute / Volume of the solution in litres
Molar mass of CaCl₂ = 110.98 g/mol
Given mass = 16.4 g
Number of moles = 16.4 / 110.98 = 0.147
750.0 mL = 0.75 L
Molarity = 0.147 / 0.75 = 0.196 mol L⁻¹
Thus the molarity is 0.196 mol L⁻¹.

If 8 moles of magnesium chloride react with enough aluminum, how many moles
of aluminum chloride are produced?
If 8 moles of magnesium chloride react with enough aluminum then the amount of aluminum chloride produced is 5.3 mole.
What is aluminum?Aluminum is defined as a chemical substance with the atomic number 13 and the symbol Al. Aluminum has a density that is around one third that of steel, which is lower than that of most common metals. It has a strong affinity for oxygen, and when exposed to air, creates a protective oxide coating on the surface.
3 moles MgCl2and 2 moles Al will produce 3 moles Mg and 2 moles AlCl3.Therefore, if 8.0 moles of MgCl₂ react, the amount of ammonium chloride that may hypothetically be created can be calculated using the mole ratio between MgCl₂ and AlCl₃ .
8.0 mole MgCl₂ x 2 mole AlCl₃ / 3mol MgCl₂
= 5.3 mole AlCl3
Thus, if 8 moles of magnesium chloride react with enough aluminum then the amount of aluminum chloride produced is 5.3 mole.

Why is it important for some skateboarding ramps to be tall? Use the terms "potential energy" and "kinetic energy" in your answer. plsssssss help meeee Plzzz in kids words
Explanation:
Yw ❤
Shorter people have a lower center of gravity. Taller people have a higher center of gravity. A lot of skateboarding tricks depend on the center of gravity.
What is kinetic energy?
Kinetic energy is a form of energy it possess when any object or person is in motion . It can be defined as the work needed to be done to produce a motion in a object from rest position.
If we want to acceleration in an object then we must apply a force on a object to give motion so we can say that we required to do work for acceleration and then we can say that required is equal to kinetic energy.
Mathematically
Kinetic energy =1/2mv^2
Where
m = mass of object.
v = velocity of object
Kinetic energy is vector quantity it means that it have both i.e magnitude and vector.
S.I unit of Kinetic energy is Joule.
Therefore, Shorter people have a lower center of gravity. Taller people have a higher center of gravity. A lot of skateboarding tricks depend on the center of gravity.

What is the percent yield of LiCl if I produced 30.85g LiCl and my theoretical yield was calculated to be 35.40g LiCl?
Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
[tex]\frac{Actual}{Theoretical} *100[/tex]
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
[tex]\frac{30.85}{35.40} *100\\\\ =87.15[/tex]
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.

A gas has a volume of 590 mL at a temperature of –55.0°C. What The temperature be if the volume expands to 15L at constant pressure?
Answer:
5542.37 K
Explanation:
Given that,
Initial volume, V₁ = 590 mL
Initial temperature, T₁ = -55°C = -55 + 273 = 218 K
Final volume, V₂ = 15 L
We need to find the final temperature of the gas. The relation between the volume and the temperature is given by :
[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]
Where
T₂ is final volume of the gas
Put all the values in above relation,
[tex]T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{15\ L\times 218\ K}{590\times 10^{-3}\ L}\\\\T_2=5542.37\ K[/tex]
So, the required temperature is equal to 5542.37 K.
