What is the total mass of products in the methane reaction CH₄ + 2O₂ $\rightarrow$ CO₂ + 2H₂O?

Question

Quizplus · Accepted Answer

The total mass of products in the given reaction is the sum of the masses of CO2 and 2H2O. The molar mass of CO2 is 44 u (C=12, O=16x2=32, 12+32=44) and the molar mass of H2O is 18 u (H=1x2=2, O=16, 2+16=18). Since there are two H2O molecules, their combined mass is 36 u (18x2). Adding the masses of CO2 and 2H2O gives 44 u + 36 u = 80 u.
