Well, I know the formula of sucrose....

Explanation:

$\text{Sucrose} \equiv {C}_{12} {H}_{22} {O}_{11}$...whose formula mass is $342.31 \cdot g \cdot m o {l}^{-} 1$..

$342.31 \cdot g \cdot m o {l}^{- 1} = \left\{12 \times 12.01 + 22 \times 1.008 + 11 \times 16\right\} \cdot g \cdot m o {l}^{-} 1$

From where will you get the atomic masses if they are not quoted to you?

I don't know the formula of palmitic acid, and am too lazy to look it up..
