SHOW WORK FOR ALL CALCULATIONS. CIRCLE ANSWERS WITH UNITS.
1) What is the pressure of 0.350 grams of argon occupying 500.0mL at 30.0oC?
2) Determine the number of moles of chlorine gas that occupy 4.60 L at 100.0oC and 44,800mmHg.
3) Calculate the volume occupied by 5.60 moles of nitrogen at 38.0oC and 0.900 atm.
4) What is the volume of 25.0 grams of H2 at STP conditions?
5) Determine the pressure in atm when 56.0 g of CH4 occupies a 300.0 mL container at 100.0oC.
6) What number of grams of H2 will occupy 100.0 L at 35.0oC and 253kPa?
7) What is the pressure in mmHg of 126.0 grams of carbon monoxide gas in 34.5 L at 55.0oC?
8) What is the pressure in atm of 6.20g of helium gas at 18.0oC and occupying 4.55x103mL?
9) What is the volume (in L) of a 71.0 g sample of chlorine gas at STP?
10) Calculate the volume (in L) of 4.00g of helium atoms at 760mmHg and 273K.
Compare your answers to 9) and 10). You should have calculated the same volume! (If not, go back
and check your work until both volumes are the same!!) Once the volumes are equivalent, you have
successfully determined the: Standard Molar Volume of a Gas
The volume occupied by 1 mole of a gas at STP: (________ K and ____ atm) = ____________
