Question

A sample of propane, a component of lp gas, has a volume of 46. 8 l at 294 k and 821 torr. What is its volume at stp?.

Answer 1

The volume of propane sample at STP condition will be 51.2 L which can be determined by ideal gas equation.

We know that from ideal gas equation,

PV= nRT

Pressure is P.

Volume is V. (in Liters)

n is the number of moles

the gas constant R, and the temperature T which is in Kelvins

Given,

P= 821 torr

T= 294 K

V= 46.8 L

Also,

n=  PV/ RT

n= 821× 46.8/  62.36 × 294

n= 2.095

Thus calculating volume at STP,

At STP,

P= 1 atm T= 298K

V= nRT/P

V= 2.095 × 0.0821 × 298/ 1

= 51.2 L

So, the volume at STP will be 51.2 L
