Ge Rent Exotic Car in M 32 of 35 Acompound is 40 0%C, 6 70% H, and 53 3% O by mass Assume that we have a 100-g Part A What are the subscripts in the empirical formula of this compound? Enter the subscripts for C, H and O, respectively, separated by commas (e.g-5,6,7) View Available Hintts) 1,2.1 Correct The emplrical formula of this compound is CH2C Part The molecular formula mass of this compound is 90 0 amu What are the subscripts in the actual molecular formula? Enter the subscripts for C. H and O, respectively, separated by commas (e.g. 5,6,7) View Available Hint(s) 201 PMExplanation / Answer
From part a
Empirical formula = CH2O
Formula weight of Empirical formula = 30
Molecular mass = 90
Multiplying factor = 90/30 = 3
Molecular formula = ( CH2O)3
= C3H6O3
