Calculate the molecular mass of sucrose (C12H22O11) molecule?

A.342 amu✓ Correct

B.343 amu

C.341 amu

D.340 amu

Explanation

The individual mass of carbon is 12 amu, the individual mass of hydrogen is 1 amu & the individual mass of oxygen is 16 amu. But sucrose has 12 carbons, 22 hydrogens and 11 oxygens, that is 12 x 12 + 22 x 1 + 11 x 16 = 342 amu.
