a. Determine the empirical formula for the compound.
b. Determine the molecular formula for the compound.
Empirical formula is the skeletal version of the molecular formula of a compound.
The number of moles of a substance is the given mass of the substance upon its molar mass.
For determining empirical formula mass ,we calculate mole ratio of elements . Then make the ratio as whole number by dividing with a suitable number to get empirical formula .
Then we calculate no of empirical formula units per molecule by dividing molar mass by empirical formula mass.
