2. Which of the following steps are in the correct order for how to calculate the molar mass of a carbon dioxide (CO2) molecule?

Question

*
A. Carbon has a mass of 16, Oxygen is 12x2, 16+24 equals the molar mass
B. Carbon has a mass of 12, Oxygen is 16x2, 12+32 equals the molar mass
C. Add Carbon and Oxygen's atomic masses together 12+16 to get molar mass
D. Divide Oxygen's mass by Carbon's mass and multiply by 2

Answer 1

The correct order is:
C. Add Carbon and Oxygen's atomic masses together 12+16 to get the molar mass
