Answer:

62.00

Explanation:

H2 means that there are two moles of hydrogen so multiply the atomic mass by two (1.01 × 2 = 2.02)

C only has one mole sp leave 12.01 alone

And multiply oxygen by 3 because there are three moles of oxygen (15.99 × 3 = 47.97)

Add them all together!

2.02 + 12.01 + 47.97 = 62.00 for molar mass
