Molar mass = 305.42 g/mol

C = ( 12 x 18 / 305.42 ) x 100 => 70.72 % of C

H = ( 1 x 27 / 305.42 ) x 100 => 8.84 % of H

N = ( 14 x 1 / 305.42 ) x 100 => 4.58 % of N

O = ( 16 x 3 / 305.42) x 100 => 15.71% of O

hope this helps!

Answer:

Explanation:  C_{18}H_{27}NO_{3}  is an organic compound with a nitro group present in it.

Given that the molar mass of the compound is 305.42 g/mol.

Mass percent of element is calculated by the mass of element divided by the total mass of the substance multiplied by 100.

Mass percent of carbon = (12 x 18) / 305.42 x 100 = 216/ 305.42 x 100 = 70.72%

Mass Percent of Hydrogen = (1 x 27) / 305.42 x 100 = 27/ 305.42 x 100 = 8.84%

Mass Percent of Nitrogen = (1 x 14)/ 305.42 x 100 = 14/ 305.42 x 100 = 4.58%

Mass Percent of Oxygen = (3 x 16)/ 305.42 x 100 = 48/ 305.42 x 100 = 15.71%
