What is the mass of 33.6 liters of SO3 gas?
| November 19, 2020 | education
m – mass of matter
v – amount of substance
Mr – molecular weight
V is the volume of the substance
22.4 – molar volume of gases
First you need to find the amount of substance by the formula v = V / 22.4
v = 33.6 / 22.4 = 1.5 mol
To find the mass, use the formula m = Mr * v
Mr (SO3) = 80 g / mol
m = 1.5 * 80 = 120 g
Answer: 120 g.
