Each molecule of testosterone contains 19 atoms of carbon (plus other atoms). The mass percent of carbon in testosterone is 79.1
Xelga [282]

Answer:

The answer to your question is letter E. 288.4 g/mol

Explanation:

Data

Number of carbons = 19

mass percent of carbon = 79.12

molar mass = ?

Process

1.- Calculate the molar mass of 19 atoms of carbon

Atomic mass of carbon = 12 g

Atomic mass of 19 atoms of carbon = 228 g                            

2.- Use proportions to calculate the mass of testosterone

                        228 g ---------------  79.12 %

                           x      --------------      100 %                          

                          x = (228 x 100) / 79.12

Simplify

                          x = 22800 / 79.12

Molar mass of testosterone = 288.2 g
