Answer to Question #43442 in Physical Chemistry for ashley

Question

A gas sample occupies a volume of 1000 mL at 40 degrees celsius and a pressure of 760 torr. If , at the same temperature, the pressure were decreased to 380 torr, what volume would result?

a) 500 mL

b) 1000 mL

c) 1500 mL

d) 2000 mL

Answer 1

According to the Boyle's law,
P₁V₁ = P₂V₂
Hence, we can calculate the gas volume:
V₂ = P₁V₁/P₂ = (760 torr * 1000 mL) / 380 torr = 2000 mL
So, the correct option is (d): 2000 mL
