Let’s begin the discussion!

How many moles of gas occupy 58 L at a pressure of 2.2 atmospheres and a temperature of 313 K?

Answer :

Given Information ,

  • Volume ,V = 58 L
  • Pressure ,P = 2.2 atm
  • Temperature ,T = 313

We have to find the number of moles .

We use here " Ideal Gas Equation" which is

  • PV = nRT

where

n is number of moles

R is universal gas Constant

T is temperature

P is pressure

V is volume

On substituting the value we get

➣ 2.2 × 58 = n × 0.0821 × 313

➣ 127.6 = n × 25.70

➣ 127.6/25.70 = n

➣ 4.96 = n

➣ 5 ≈ n

So, the number of moles are 5 .
