Answer to Question #108644 in General Chemistry for Adri

Question

A gas sample has a volume 0f 125.0 mL at 1.47 atm and 32oC. What is the volume at STP?

Answer 1

Solution.

V₁=125.0 mL;

P₁=1.47 atm;

T₁=305 K;

P₂=1.00 atm;

T₂=273 K;

V₂ - ?

(P₁V₁)/T₁=(P₂V₂)/T₂; $\implies$ V₂=(P₁V₁T₂)/(T₁P₂);

V₂=(1.47 atm$\sdot$125.0 mL $\sdot$ 273 K)/(305 K$\sdot$ 1.00 atm)=164.5 mL.

Answer: V₂=164.5 mL
