Question

Calculate the approximate temperature of a 0.50 mol sample of gas at 2.7 atm and a volume of 1.20L

Answer 1

79.0 K

Step-by-step explanation:

Assuming the gas behaves like an ideal gas, we can solve this problem by using the following formula:

• PV = nRT

Where:

• P = 2.7 atm

• V = 1.20 L

• n = 0.50 mol

• R = 0.082 atm·L·mol⁻¹·K⁻¹ (it is a constant)

• T = ?

We input the data:

• 2.7 atm * 1.20 L = 0.50 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * T

And solve for T:

• T = 79.0 K
