The molecular formula of aspartame, the artificial sweetener marketed as NutraSweet, is C14H18N2O5. a. What is the molar mass of aspartame? b. How many moles of aspartame are present in 1.00 mg of aspartame? c. How many molecules of aspartame are present in 1.00 mg of aspartame? d. How many hydrogen atoms are present in 1.00 mg of aspartame?

a-294

b-3.401×10^-6

c and d - 2.048×10^18

Explanation:

multiply the RAM if each individual element by the molecular number eg (c-12×14) then add to get the molar mass

b-molar mass is equal to grams/mol so convert 1 mg to g to get 0.001 and divide it by the molar mass

c/d-1 mol of anny substance has 6.023×10^23(ions,molecules etc) therefore what about the moles present here so

(3.401×10^-6)×(6.023×10^23)

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
