Answer:
Explanation:
<u>1) Determine the molar mass of the heptane</u>
element # of atoms atomic mass total mass
C 7 12.011 g/mol 7×12.011 g/mol = 84.077 g/mol
H 16 1.008 g/mol 16×1.008 g/mol = 16.128 g/mol
-------------------
Molar mass = 100.205 g/mol
<u>2) Percent of carbon, %</u>
- % = (mass of element / molar mass )×100
= (84.077 g/mol / 100.205 g/mol )×100 = 83.83 %
- Round to two significant figures: 84% ← answer
