Question
Gas law problem? 4. What pressure in atmospheres will be exerted by 0.312 moles of an ideal gas at 42 degree C in a volume of 58 4mL? 5. How many moles of gas will occupy 5.0 liters at STP? 6. At what temperature must you hold 12.8 grams of O2 gas to have a pressure of 0.20 atm and a volume of 0.50 liters? 7. What is the density, in g/L, of Cl2 gas at STP? 8. What is the mass of a N2 gas sample if its volume is 6.0L, the temperature is -23 degree C and the pressure is 2.0 atm, 9. What is the molar mass of a gas if 268ml at 69 degree C and 17.9 torr pressure weighs 0.156 grams? 10.What is the molar mass of a gas if its density at 289K and 0.980 atm was found to be 2.66g/L 11. lt was found that at 25 degree C the density of N20 gas was 1.73 g/L. What was the pressure in atmospheres? 12. How many grams of acetylene, C2H2, will occupy 1.00L at 24 degree C and a pressure of 742 torr, 13. What will the total pressure be if a 3.0L container at -123 degree C contains 2.8g N2, 2.2g CO2 and 0.02g of H2? 14.How many moles of gas are present if, when the gas is collected over water at 26 degree C, it has a total pressure of 755 torr and the volume is 3.5 liters? The vapor pressure of water at this temperature is 25 torr.Explanation / Answer
5.
1 mole of gas occupies 22.4 litre at STP
so 5 litre will occupy 1*5/22.4=0.223 moles
