What is the effect of the following on the volume of 1 mol of an ideal gas?
(a) The pressure changes from 760 torr to 202 kPa, and the temperature changes from 37°C to 155 K.

Respuesta :

The volume will decrease by a factor of 4

What is the effect of the following on the volume of 1 mol of an ideal gas?

Given:

P₁ = 760 KPa

P₂ =202KPa

The temperature changes from 37°C to 155 K

P₁ = 760 torr.

Ideal gas equation:

PV = nRT

where;

nR is constant

P= pressure

V= volume

T= temperature

n = number of moles

On adding values:

(P₁V₁/T₁)=(P₂V₂/T₂)

V₁/V₂ = P₂/P₁ * T₁/T₂

V₁/V₂ = (202/101)*(310/155)

V₁/V₂ = 4

Therefore, the volume has decreased by a factor of 4

What volume, at STP, does one mole of any ideal gas occupy?

The most typical illustration is the molar volume of a gas at STP, which is equal to 22.4 L for 1 mole of any ideal gas at a temperature of 273.15 K and a pressure of 1.00 atm.
