A sample of oxygen occupies 40L under a pressure of 1200 torr at 300. If temperature is kept constant, what volume would the
Answer:
V₂=80L
Explanation:
P₁ V₁ = P₂ V₂
P₂ P₂
Cancel out the two P₂ in the right side.
V₁ 40L
P₁ 1200 torr
P₂ 600 torr
V₂ ?
V₂ = (1200 torr) (40L)
600 torr
V₂ = 80L
Cancel out the two torr, now times the 1200 to 40 and you get the 48,000. And divide it to 600, 600 ÷ 48,000 equals 80L. Also no need to add the 300 if it's a temperature because in boyle's law you only need volume and pressure.
