A) 0.57 (M)
B) 5.7 (M)
C) 11.4 (M)
D) 1.14 (M)
Correct Answer: A
Solution :
From molarity equation \[{{M}_{1}}{{V}_{1}}+{{M}_{2}}{{V}_{2}}=M{{V}_{(total)}}\] \[2\times \frac{10}{1000}+0.5\times \frac{200}{1000}=M\times \frac{210}{1000}\] \[120=M\times 210\] \[M=\frac{120}{210}=0.57M\]You need to login to perform this action.
