Answer: 80%
Explanation:
Relative atomic mass of
C - 12 H - 1 O - 16
C - ( 12 x 10 ) H - ( 1 x 14 ) O - 16
total molar mass = 120 + 14 + 16
= 150
150 (molar mass) = 55.4g (mass)
total molar mass of carbon = 120
150 = 55.4
120 = x
x = [tex]\frac{(120)(55.4)}{150}[/tex]
= 44.32g
percentage = [tex]\frac{44.32}{55.4}[/tex]×100
= 80%
