Question

Calculate empirical and molecular formula of carbon 40.68%

Answer 1

Answer:

Empirical Formulas•When a compound’s percent composition is known, its formula can be calculated.•First, determine the smallest whole-number ratio of the moles of elements in the compound.–This ratio gives the subscripts in the empirical formula.•The empirical formula for a compound is the formula with the smallest whole-number mole ratio of the elements.–The empirical formula might or might not be the same as the actual molecular formula! –The empirical formula = molecular formula for IONIC COMPOUNDS -ALWAYS
