1 molar(no.of moles of solute per litre) Mg has molarity=density/molar mass density=molarity*molar mass =1mol/l *24.3051 g/mol =1/1000ml*24.3051 g/mol calculate the actual density for 1mole in g/ml for 1 mole of Mgo to be produced i need 1 mole of mg so for that many grams of Mgo calculate the amount of 1M mg required by variation method then for 1M density u require x g of Mg so for 1.74g/ml how much?
