Divide each wight by the relative atomic mass
C = 216 / 12 = 18
H = 36 / 1 = 36
O = 288/16 = 18
Ratio of C:h:O = 1:2:1
Empirical formula is CH2O Could be formaldehyde HCHO.

M = no. of moles of the solute present in one kg of solution
Let the weight of amount of solute be “w” and its molecular mass be “M”
Let the mass of the solvent in the given question be “x”
