The molecular formula of a compound with molar mass of 44.01 g/mol and empirical formula of CO2 is
CO2
calculation
First calculate the empirical formula mass
={12.01 + (16 x2)}n= 44.01 g/mol
then divide the molecular formula mass with empirical formula mass
that is 44 g/mol÷ 44 g/mol =1
then multiply each subscript in empirical formula with 1 (answer in step 2)
that is C = 1 x1=1
O= 2 x1 =2
therefore the molecular formula = CO2
