A) 100
B) 150
C) 120
D) 200
Correct Answer: D
Solution :
Molarity \[=\frac{W(gm)\times 1000}{V(ml)\times \text{molecular weight}}\] \[0.25=\frac{1.25\times 1000}{25\times \text{molecular weight}}\] \[\therefore \] Molecular weight \[=\frac{1.25\times 1000}{0.25\times 25}=200\].You need to login to perform this action.
