A mass of gas has a volume of 380 cm3 at a pressure of 560 mm Hg and a temperature of 7C. What is its bolume at s.t.p.?

Answer 1

P = 560/760= 0.73684 atm
T = 280 K

At STP (To = 273 and Po = 1 atm), the volume at (P,T) gets mutiplied by
(To/T)(P/Po) = (273/280(1/0.73684)
= 1.323

That makes the new (STP) volume 503 cm^3

Answer 2

273 cm3
