Question

For a 0.00554 mol sample of H2, P=23.44 torr and T=557 K. What is its volume?

Answer 1

Answer:

The volume is 8,22 liters.

Explanation:

The unit of pressure (from Torr to atm) must be converted: 760 Torr = 1 atm

760 Torr---1 atm

23,44Torr--x= (23,44Torr x 1 atm)/760 Torr= 0,0308 atm

PV=nRT V= (nRT)/P

V=(0,00554 mol x 0,082 l atm/K mol x 557 K)/ 0,0308 atm

V=8, 22 L
