Use the Ideal Gas Law to calculate the moles of hydrogen. The Ideal Gas Law is PV=nRT. We can rearrange the Ideal Gas Law to get n=PVRT. Calculate the moles of CaH2. Calculate the mass of CaH2.

What is pressure?

The SI unit for pressure is the pascal (Pa), which is equal to one newton per square meter (N/m2) of force per unit area of the surface. An object's pressure is inversely proportional to the area it is pressing on and inversely proportional to the force it applies.

What elements influence pressure?

Pressure rises when the number of gas molecules rises while the volume of the container stays the same. Gas pressure rises as container volume decreases. The pressure rises as the temperature of a gas inside a rigid container rises.
