Question

what pressure in a 30.0-L cylinder filled with 38.5 g of oxygen gas at a temperature of 329 K?

Answer 1

Volume of cylinder with gas filled = 30L Temperature = 329k Flost we will calculate number of moles of oxygen, number of moles = liven mass Molar mars n = 38.5 g = 1.2 moles O. 32 g/mol for presure, using [PV= net where R=0.0821 L.atm/molok Putting all values, 1.2 moles X 0 10821 fatm x 3298 304 x molek NRT P = 32.413 atm 30 = 1.08 atm Pressure = 1108 atm
