Expert Answer
Mol. wt. of CaCl2.2H2O is 147 gms.
10 mmole means 0.01 mole
Now, 1 mole of CaCl2.2H2O has 147 gms
10 mmole means 0.01 mole
Now, 1 mole of CaCl2.2H2O has 147 gms
So, 0.01 moles will have = 1.47 gms
means we have 1.47 gms of CaCl2.2H2O per litre i.e. 1000 ml.
So, 1000 ml has 1.47 gms
1 ml will have = 0.0014 gms
means we have 1.47 gms of CaCl2.2H2O per litre i.e. 1000 ml.
So, 1000 ml has 1.47 gms
1 ml will have = 0.0014 gms
