Question

Calculate the volume of the gas, in liters, if 1.65 mol has a pressure of 1.22 atm at a temperature of -5 ∘C.

Answer 1

Answer:

36.2 L is the volume of the gas

Explanation:

We apply the Ideal Gases Law to solve this:

P . V = n . R .T

Pressure: 1 atm

V: Our unknown value

n: the number of moles, 1.65 mol

R: Universal Gases Constant (0.082 L.atm/mol.K)

T: Absolute T°, is the T° in K (T°C + 273) → -5°C + 273 = 268K

Let's replace:

1 atm . V = 1.65 mol . 0.082 L.atm/mol.K . 268K

V = (1.65 mol . 0.082 L.atm/mol.K . 268K) / 1 atm → 36.2 L
