Question

At 0°c and 760 mm hg pressure a gas occupies a volume of 100 cm3

Answer 1

actually your questions is not properly correct I think this is the solution of u r question

According to question

  V₁ = 100cc = 0.1 L 

T₁ = 273 

P₁ = 760 mm hg = 1 bar

we find,

V₂ = ?  

T₂ = 273/5 

P₂ = 1 x 1 1/2 = 3/2 bar

So from Combined gas law :  P₁ V₁ / T₁ = P₂V₂/T₂

⇒ 1 x 0.1 / 273 = 3/2 x V₂  / 273/5

⇒ V₂ = 1 x 0.1 x 273 x 2 / 273 x 5 x 3  ⇒ V₂ = 0.0134 L
