Question

What is the concentration of fecl3 in a solution prepared by dissolving 10.0 g of fecl3 in enough water to make 275 ml of solution?

Answer 1

0.225M of Fecl3

Step-by-step explanation:

No of mole=mass/molar mass

Molar mass of fecl3= 162g/Mol

No of mole= 10/162= 0.062mol

No of Mol = concentrate × volume

Concentration= n/V = 0.062/0.275

C= 0.225M of FeCl3
