Question

A container of 0.0132 moles of hydrogen gas
has a volume of 0.170 liters and a pressure
of 0.484 atm. What is the temperature?​

Answer 1

Answer:

Molar volume is the volume occupied by 1 mol of any (ideal) gas at standard temperature and pressure (STP : 1 atmospheric pressure, 0  

o

C). Show that it is 22.4 litres.The ideal gas equation relating pressure (P), volume (V), and absolute temperature (T) is given as:

PV = nRT

Where,  

R is the universal gas constant =8.314Jmol

n = Number of moles = 1

T = Standard temperature = 273 K

P = Standard pressure = 1 atm =1.013×10

∴V=nRT/P

=1×8.314×273/(1.013×10

=0.0224m

=22.4 litres

Hence, the molar volume of a gas at STP is 22.4 litres.
