Answer» question :-A composition of a organic COMPOUND found to contain 39.9% of CARBON, 6.7% of hydrogen and remaining being oxygen. The molar mass of the compound is 180. DETERMINE its empirical formula and molecular formula.Solution :-Given :-Percentage composition of carbon (C) = 39.9%Percentage composition of hydrogen (H) = 6.7%Percentage composition of oxygen (O) = 100 - ( 39.9 + 6.7 ) = 100 - 46.6 = 53.4%Simplest RATIO :-Empirical formula mass = 12 + ( 2 × 1 ) + 16 = 12 + 2 + 16 = 30 We know :-Here,Molecular formula = |
