A) 2.70 M
B) 1.344 M
C) 1.50 M
D) 1.20 M
Correct Answer: B
Solution :
[b] From the molarity equation. \[{{M}_{1}}{{V}_{1}}+{{M}_{2}}{{V}_{2}}=MV\] \[M=\frac{{{M}_{1}}{{V}_{1}}+{{M}_{2}}{{V}_{2}}}{V}\] where \[V={{V}_{1}}+{{V}_{2}}\] \[M=\frac{480\times 1.5+520\times 1.2}{480+520}=1.344M\]You need to login to perform this action.
