1% iron solution??
Dissolve 1.70g of iron III chloride in 99 ml of distilled water. Mix well and label 1% iron.
I've tried to check the value of the iron percentage but I don't succeed.
First I've tried to find out the number of mole of FeCl3,6H2O (M=270g.mol-1) in 1.70 g and found the mass of iron 0.352 g then divide this mass by the total mass (1,7+99), but it doesn't work. Could anyone help me? Thanks in advance.
