Question

What is the volume at STP of a 102g sample of propane gas, C3H8

Answer 1

Hey there!

Molar mass C3H8 => 44.0956 g/mol

Therefore:

44.0956 g ---------------- 22.4 L ( at STP )

102 g ----------------------- Volume C3H8 ??

Volume = 102 * 22.4 / 44.0956

Volume = 2284.8 / 44.0956

Volume = 51.81 L

hope this helps!
