OpenStudy (somy):

molarity = mole / volume volume has to be in Liters so convert mL to L now use the formula and find mole from it since u have molarity (M) and volume (L) so u get mole now mole = mass / molecular mass so now find mass using mole mass= mole x molecular mass u know mole and u know molecular mass by calculating it using periodic table since u know what is your compound and so get the mass in grams
