Ten grams of a gas occupies 12.5 liters at a pressure of 42.0 cm Hg. What is the volume when the pressure has increased to 75.0 cm Hg?

Based on the question, it is evident that the question is based on Boyle's Law which we will use to find the answer necessary.

Now, Boyle's Equation: P₁V₁ = P₂V₂

     V₂ = P₁V₁  ÷  P₂

∴   V₂  =  (12.5L × 42.0 cm · Hg) ÷ 75 cm · Hg

⇒  V₂  = 7 L
 
Thus, the volume when the pressure has increased to 75.0 cm Hg is 7 Litres.
