Question

What is the density of methane gas (CH4) at 127°C and 3.50 atmosphere

Answer 1

Answer:

1.70625 g/

Explanation:

To determine the density, use the following equation.

Density = Mass of 1 mole ÷ Volume of 1 mole

At STP, the volume of one mole of a gas is 22.4 liters. Let’s use the following equation to determine the volume of mole at 127°C and 3.5 atmosphere.

P1 * V1/T1 = P2 * V2/T2

P1 = 3.5, T1 = 127 + 273 = 400, P2 = 1, V2 = 22.4, T2 = 273  

3.5 * V1/400 = 1 * 22.4/273

V1 = 400/3.5 * 22.4/273 = 9.377289377  

To determine the density, use the following equation.

Density = 16 ÷ 9.377289377 = 1.70625 g/
