Answer 2

isnt it Divide the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.

Answer 3

no

Answer 4

empirical formula is simplest form of molecular

Answer 5

if u had molecular formula as C2H2
your empirical formula would be CH
because u can divide both C2 and H2 by 2 and get 1 for both

so to get molecular you do opposite way of this
