Propane molecular weight is 44 g/mol. Your answer is 150 grams of #CO_2#

Find the mol of propane that is combusted:

#50/44#

#=1.136# mol

It means you spent 1.136 mol of propane, to get #3times1.136# moles of carbondioxide. That is #3.41# moles of carbondioxide.

Since #CO_2# has a molecular weight of 44 grams per mol,

it means you get #44times3.41#

#=150# grams of carbondioxide you get after full combustion of propane.
