Explanation / Answer

Question 2

As per the information given, Molecular mass or Ca = 40 and Cl = 35.

The molecular weight of CaCl2 = 40 + 2(35) = 110

1 Molar solution is a solution in which 1 mole of compound is dissolved in 1 liter of solution.

One gram molecular weight of CaCl2 = 110g

When 110 g of CaCl2 dissolved in 1 liter of water will give 1 M solution of CaCl2.

Therefore, to prepare 2 liters of 1 M solution of CaCl2, the amount of CaCl2 will be required to dissolve in 2 liters of water is = 2 x 110 = 220g

So 220g of CaCl2 need to dissolve in the 2 liters of water.
