ques 23 E-J

You need to dissolve CaCl2 in water to make a mixture that is 36.0% calcium chloride by mass. If the total mass of the mixture is 545.4 g, what masses of CaCl2 and water should be used?

Mass of CaCI2 (in grams):

Mass of H2O (in grams):

Solution

Total Mass of Mixture = 545.4 gms

Mass of Dissolved CaCl2 = 36% of the total mass

=> 36/100 * 545.4 = 196.344 gms

Mass of H2O (in gms) = 545.4 - 196.344 = 349.056 gms
