CHAPTER-10   GASES

1.    Convert: 19.5psi to atm, 958torr to atm, 2.3atm to torr, 22.3psi to mmHg

2.    If P1=755mmHg, V1=2.85L, P2=885mmHg , V2=_________

3.    V1=1.08L, T1=25.40C, V2=1.33L, T2=___________________________

4.    V1=38.5ml, n1=1.55×10-3, V2=49.4ml, n2=__________________________

5.    P1=1.21tm, V1=1.58L, T1=12.20C, P2=1.54atm, T2=32.30C, V2=________________

6.    P=1.05atm, V=1.19L, n=0.112mol, T=____________________

7.    P=112torr, V=________________, n=0.241mol, T=304K

8.    An experiment shows that a 113ml gas sample has a mass of 0.171g at a pressure of 721mmHg and a temperature of 320C. Calculate the molar mass of the gas.

9.    N2=355torr, O2=128torr, He=229torr, find total pressure

10.A gas mixture has 78% nitrogen and 22%oxygen. If the total pressure is 1.12atm what are the partial pressure?

11.Calculate volume at STP of 0.298mol CO2, 38.9mol N2O

12.Calculate volume at STP of 45.2g Xe, 245mg CO2

13.Calculate mass at STP of 178ml CO2, 139cm3 Arch
