1.
A 0.50 L canister of hazardous sarin gas was discovered at an old abandoned military station. To
properly dispose of this gas, technicians must know how much gas is held in the canister. The
gas pressure is measured as 10.0 atm at room temperature (25 C.) How many moles of sarin are
held inside the canister?
2. What volume will 2.0 mol H, occupy at 40.0 C and 0.50 atm pressure?
3. When the volume of a gas sample is measured, its pressure and temperature must also be
specified.
a. Why?
b. That practice is normally not necessary for measuring the volumes of liquids or solids. Why?
