Solubility CaSO4 = grams/molar mass = mols in 100 mL.
Convert mols CaSO4 to g. g = mols x molar mass CaSO4.
a.
Total grams - grams dissolved = ?
b.
mols CaSO4 in 100 mL x (1000/100) = mols CaSO4 in 1 L and M = mols/L.
Convert mols CaSO4 to g. g = mols x molar mass CaSO4.
a.
Total grams - grams dissolved = ?
b.
mols CaSO4 in 100 mL x (1000/100) = mols CaSO4 in 1 L and M = mols/L.
