Question

Define Molarity (M)

Solution 1

Molarity

Molarity (M) is defined as the number of moles of the solute dissolved in one Litre of the solution.

It is expressed as:

Molarity (M) = `"Moles of solute"/"Volume of Solution  in Litre"`

Solution 2

It is defined as the number of moles of solute present in 1000 mL of the solution. Molarity is represented by M.

Molarity (M)  = `"Number of moles of solute"/"Volume of solution in mL" xx 1000`

or

`M = "Weight of solute"/"Molar mass of solute × Volume of solution in mL" xx 1000`

  Is there an error in this question or solution?
