Propane gas, C3H8
First, we need the molar mass of propane to solve this.
The molar mass of propane = 44.1 g/mol
(use the periodic table)
Procedure:
1 mol of Propane = 44.1 g
We want to know the mass of 2 moles of it, so we proceed like this:
1 mol C3H8 ---------- 44.1 g C3H8
2 moles C3H8---------- x
x = 88.2 g C3H8
Answer: the mas of C3H8 = 88.2 g
