A) 0.5010 M
B) 0.2897 M
C) 0.7093 M
D) 0.1428 M
E) 0.4005 M
Correct Answer: D
Solution :
0.2 molar solution, ie, 1000 mL solution contains 0.2 mol solute. \[\therefore \] 500 mL solution contains 0.1 mol solute thus, 700 mL solution contain \[\frac{0.1}{500}\times 700=0.14\text{ }mol\] \[\therefore \]Molarity of solution = 0.14 MYou need to login to perform this action.
