Question

Find the volume of 32g methane (ideal gas) at 27° c and 380 mm hg

Answer 1

Explanation:

At first we should convert the pressure from mm Hg into pascal .

380 mm Hg = 0.5 atm

0.5 atm = 0.5 × 10^5

so , P = 5 × 10^4

according ideal gas equation :-

PV = nRT

V = nRT/P

V = (2 × 8.3 × 300) / 5 × 10^4

$2 \times 8.3 \times 300 = 4980$

$4980 \div 50000 = 0.498 \div 5$

V ~ 0.1 m3 = 100 litres
