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
