Show Answer

Answer:

Correct Answer: B

Solution:

$ N=\frac{10\times sp\text{. gr}\text{. of the solution}\times wt\text{. }\text{ of solute}\times Mol\text{. wt}\text{.}}{\text{Molecular wt}\text{. of solute}\times Eq\text{. wt}\text{.}} $

$ N=\frac{10\times 1.71\times 80\times 98}{98\times 49}=27.9 $
