Question

Aspartame is a sweetner that is 160 times sweeter than sucrose (table sugar) when dissolved in water. The molecular formula of aspartame is C14H18N2O5

Answer 1

Answer:

• 294.307 g/mol

Explanation:

The first question for this statment is:

• Calculate the gram-formula-mass of aspartame.

Solution

The chemical formula is:

        $C_{14}H_{18}N_2O_5 .$

The gram-formula-mass is calculated adding the masses for all the atoms in the molecular formula:

Atom       Number of atoms      Atomic mass       Total mass

                                                            g/mol            g/mol

C                     14                              12.011              14 × 12.011 = 164.154

H                     18                              1.008              18 × 1.008 = 18.144

N                      2                              14.007             2 × 14.007 = 28.014

O                      5                              15.999             5 × 15.999 = 79.995

                                                                                ===================

                                                            Total            294.307 g/mol

Answer: 294.307 g/mol
