compound.
Go from grams to moles - --divide grams by molar mass
Go from moles to grams - --moles x molar mass
Convert g/l to g/mL - --multiply by 1000
Calculate molecular formula from a empirical formula - --First, use the molar mass and the empirical
formula molar mass to determine n, the number you must multiply the empirical formula by; Second,
multiply the coefficients in the empirical formula by n to find molecular formula.
