Which one of the following equations is used to get molarity (M) of a standard solution ?

  1. (a) \(M=\frac{\text{Weight of solute in gm}}{\text{Molecular weight of solute}}\times\frac{1000}{\text{Volume of solution (mL)}}\)
  2. (b) \(M=\frac{\text{Weight of solute in gm}}{\text{Equivalent weight of solute}}\times\frac{1000}{\text{Volume of solution (mL)}}\)
  3. (c) \(M=\frac{\text{Volume of solute (mL)}}{\text{Molecular weight of solute}}\times\frac{1000}{\text{Weight of solution (gm)}}\)
  4. (d) \(M=\frac{\text{Volume of solute (mL)}}{\text{Equivalent weight of solute}}\times\frac{1000}{\text{Weight of solution (gm)}}\)
