Question

Quizplus · Accepted Answer

To find the molar mass of aspartame, we need to add the atomic masses of all the elements present in the molecule.

C: 1 x 12.01 = 12.01
H: 14 x 1.01 = 14.14
N: 2 x 14.01 = 28.02
O: 5 x 16.00 = 80.00
S: 2 x 32.06 = 64.12
U: 6 x 1.01 = 6.06
B: 2 x 10.81 = 21.62
P: 2 x 30.97 = 61.94

Adding all of these up, we get:
12.01 + 14.14 + 28.02 + 80.00 + 64.12 + 6.06 + 21.62 + 61.94 = 293.91

Rounding to the nearest integer, we get 294 g/mol. Therefore, the answer is C.
