Calculate the formula mass of the metal hydroxide
Average titration value= 31.2
Concentration of HCl= 3.65 g/dm3
Solution contained 5.0g metal hydroxide per dm3
3.65 x 31.2/1000 g HCl Ξ 5.0 x 25/1000 g MOH;
36.5 g HCl reacts with 5.0 x 25 x 10/31.2 g MOH = 40.1
Where did they get the 25 from???
what the full question with the equation it may be a standardised solution
It might be the relative atomic mass but im not sure...
In the question it gives you the relative atomic masses of H=1, Cl=35.5, O=16
MOH + HCl ---> MCl + H20
