A 6 l volume of ideal neon gas (monatomic) is at a pressure of 3.2 atmospheres and a temperature of 310 k. the atomic mass of neon is 20.2 g/mol. in this situation, the temperature of the gas is increased to 410 and the volume is increased to 8.0 l. the final pressure of the gas, in atmospheres, is closest to:

Answer is: the final pressure of the gas is closest to 3,17 atm.

p ₁ = 3,2 atm.

T₁ = 310 K.

V₁ = 6 L.

p₂ = ?

T₂ = 410K.

V₂ = 8,0 L.

Use combined gas law - the volume of amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.

p ₁V₁/T₁ = p₂V₂/T₂.

3,2 atm · 6,0 L : 310 K = p ₂ · 8,0 L : 410 K.

0,0619 = 0,0195p ₂.

p ₂ = 3,17 atm.
