How do you find the empirical formulas?
Calculate the empirical formula.
- In any empirical formula problem you must first find the mass % of the elements in the compound.
- Then change the % to grams.
- Next, divide all the masses by their respective molar masses.
- Pick the smallest answer of moles and divide all figures by that.
How do you calculate hydration state?
Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical (actual) percent hydration (percent water) can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.
