For a compound with a molecular formula of C11H20O2, what is the formula mass?

The molecular formula of the compound is - C₁₁H₂₀O₂

formula mass is the sum of the products of the relative atomic masses of the elements by the number of atoms of the corresponding element

r. a. m - relative atomic mass

the elements making up the compound with their relative atomic masses are;

C - 12 r. a. m - 11 C atoms

H - 1 r. a. m - 20 H atoms

O - 16 r. a. m - 2 O atoms

the formula mass - (11 x r. a. m of C) + (20 x r. a. m of H) + (2 x r. a. m of O)

formula mass = (11 x 12) + (20 x 1) + (2 x 16)

= 132 + 20 + 32

= 184

formula mass of compound is 184
