## Question:

How would you prepare 1.10 L of a 0.70-M solution of each of the following?

1) NiCl2 from the salt NiCl2 x 6H2O :

Dissolve _____ g NiCl2 x 6H2O in water, and add water until the total volume of the (Solution or Water) is 1.1 L.

2) Sodium Carbonate from the pure solid :

Dissolve _____ g Na2CO3 in water, and add water until the total volume of the (Solution or Water) is 1.1 L.

## Preparation of Solutions:

One of the requirements in preparing a solution is that the measurement should be done accurately. Even if the solution is used for qualitative purposes, the components of the solution should still have accurate amounts because for some, the reactivity of the solution depends on the concentration.
