Concept explainers
Interpretation:
To find the molecular formulas of benzene and acetylene.
Concept Introduction:
Molecular formula is found by multiplying a whole number to the empirical formula. The whole number is found by dividing the molar mass with the empirical formula mass.
To find the empirical formula we first convert the given mass % of each element to grams, and then divide the mass in grams of each element with its respective
