How would you make 1 liter of a 1 m solution of cacl2 (molecular weight =111 g)?

Dissolve 111 grams of CaCl2 in 1 Liter of water and it would give 1 M solution.

Explanation:

This is simple, if you want to make 1M solution of any substance just take one mole of that substance and dissolve it in one decimeter cube or one liter of water.

And one mole of a substance equal to the molecular weight of that substance taken in grams.

So you have to dissolve 111 grams of CaCl2 in one liter water and it would make 1 M solution of CaCl2.

materials water oxygen those are the things i can think of in this moment.
