Capsaicin, the compound that gives the hot taste to chili peppers, has the formula c18h27no3. its molar mass is 305.42 g/mol. calculate the mass percent of each element in the compound.

Explanation:    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%

it's c. elements are placed in rows based on how may valencies electrons have.
