Question

Find the number of moles of gas that would occupy 102
litres at a pressure of 3.7 atm and a temperature of 500 K.​

Answer 1

Answer:

According to the ideal gas equation

pv = nrt

n = pv/rt

n= 3.7× 102 ÷ 500×2

n= 0.3774

Answer 2

Answer:

9.20 mol

Explanation:

Given :

Volume V = 102 L

Pressure P = 3.7 atm

Temperature T = 500 K

We have to find numbers of moles n :

From ideal gas equation :

P V = n R T

= > R = 0.082 L atm mol⁻¹ K⁻¹

Putting values in equation we get :

3.7 × 102 = n × 0.082 × 500

= > n = 3.7 × 102 / 0.082 × 500

= > n  = 377.4 / 41 mol

= > n = 9.20 mol

Therefore , number of moles of gas is 9.20 mol.
