A) 0.97 N
B) 0.142 N
C) 0.194N
D) 0.244 N
Correct Answer: C
Solution :
We know that 1g equivalent weight of \[NaOH=40\,g\] \[\therefore \]\[40\,g\]of\[NaOH=1\,g\]eq. of \[NaOH\] \[\therefore \] \[0.275\,g\]\[NaOH=\frac{1}{40}\times 0.275\,eq.\] \[=\frac{1}{40}\times 0.275\times 1000\] \[=6.88\,\text{meq}\] \[\underset{(HCl)}{\mathop{{{N}_{1}}{{V}_{1}}}}\,=\underset{(NaOH)}{\mathop{{{N}_{2}}{{V}_{2}}}}\,\] \[{{N}_{1}}\times 35.4=6.88\] \[(\because \,meq=NV)\] \[{{N}_{1}}=0.194\]You need to login to perform this action.
