Problem- Upon combustion, a 1.000 g sample of a compound containing hydrogen, oxygen and carbon produced 1.50 g CO2 and 0.41 g H2O.
a. Find the empirical formula. This empirical formula should be written with whole numbers.
b. The molecular weight is found to be 176.12 g/mol. Determine the molecular formula
I am in urgent need of solution of above problem with complete explanation
