A solution containing 10 mmol CaCl2 is diluted to 1L.calculate no of grams of CaCl2.2H2O permilimeter

Question

for final solution.

Answer 1

Perhaps you mean per milliliter? In any case, you need to say what volume of the original solution was diluted to 1L.........

Answer 2

The molecular weight of CaCl2.2H2O is 40+71+36 = 147.  There are thus 1.47 grams of the stuff in your 1 liter bottle, and 1/1000 of that, 1.47 milligrams, in a milliliter.  Previous answer has ignored the water of hydration.

Answer 3

molwt cacl2 is 111.1gms.

10mmole = 0.01 mole

1 mole has 111.1gms

0.01 moles -- (?) = 1.111 gms

u have 1.111 gms per liter means 1000 ml.

1000 ml has 1.111 gms

1 ml has (?) = 0.001 gms
