Question

A reactionyields 0.00959mol of O2 gas. What volume will the gas occupy if it is collected at 23.0◦C and 1.19 atm pressure? Answer in units of mL.

Answer 1

PV = nRT

P = 1.9 atm

V = ?

n = 0.00959 mol

R = 0.0821 Latm/Kmol

T = 23 + 273 = 296K

Solve for V = nRT/P and convert to mls by multiplying by 1000
