Question

30 ml of 0.1m ki and 10 ml of 0.2m agno3 is mixed the solution is then filtered out assuming no change in volume the solution will freeze at

Answer 1

Explanation:

Since the density is equal to the mass divided by the volume, so the mass will be equal to the multiplication of the density and mass. Hence, we have given the one mole of the water in the problem. =6.023×1024 electron. Hence the total number of electrons present in 18mL water is 6.023×1024.
