A 100ml sample of sodium bromide containde co104.62g of sodium bromide. upon evaporation, 6.280g of reside was obtained. frome this data calculate each of the folowing for the solution;
a density of the solution
b percent by mass of sodium bromide in the solution
concentration of sodium bromide in grams per 100ml of water.
D grams of sodium bromide per liter of solution
E molarity of the solution
