Aspartame is a sweetner that is 160 times sweeter than sucrose (table sugar) when dissolved in water. The molecular formula of a
NikAS [45]

Answer:

  • <u><em>294.307 g/mol</em></u>

Explanation:

The first question for this statment is:

  • <em>Calculate the gram-formula-mass of aspartame. </em>

<em />

<h2>Solution</h2>

The chemical formula is:

        C_{14}H_{18}N_2O_5 .

The <em>gram-formula-mass </em>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

What's a word equation
Yuri [45]
A word equation is a chemical reaction described using words.
A common example is the act of photosynthesis - the process plants use to make glucose (sugar) to use as 'food'.
Plants convert water and carbon dioxide into oxygen and glucose.
A word equation to express this is:
Water + Carbon Dioxide → Glucose + Oxygen
The other type of equation is a symbol equation - this uses the symbols of the elements instead of the common names:
H₂O + CO₂ → C₆H₁₂O₆ + O₂
There is also a balanced version:
6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂
<em>If you want information on the balanced symbol equations, feel free to PM me.</em>
