Let's call the atomic mass unit u.
1 u = 1.6605*10^(-27) kg
Mass of C is 12 u
Mass of H = 1 u
Mass of N = 14 u
Mass of O = 16 u
The artificial sweetener NutraSweet is a chemical called aspartame (C14H18N2O5).
(a) What is its molecular mass (in atomic mass units)?
u
(b) What is the mass (in kg) of an aspartame molecule?
kg
I know I have to get the totally mass of the aspartame, but I'm unsure how to work the problem.

Do I multiply the 1 u by the mass of the aspartame then add them up .
and for the mass of kg what is the conversion factor.
and for the mass of kg what is the conversion factor.
Mass of C14H18N2O5 is:
14 times mass of C + 18 times mass of H etc.
Mass of C is 12 u as listed above.
Then you get an answer for the mass in terms of u. If then substitute u = 1.6605*10^(-27) kg you get the mass in kg.
14 times mass of C + 18 times mass of H etc.
Mass of C is 12 u as listed above.
Then you get an answer for the mass in terms of u. If then substitute u = 1.6605*10^(-27) kg you get the mass in kg.
I divided the 1.6605*10^-27 by 294.13 and got 1.77*10^-25kg, but that doesn't seem to be the right answer.
