Question

Molarity is defined as

• A. the number of moles of solute dissolved in one $d{m}^3$ of the solution
• B. the number of moles of solute dissolved in $1kg$ of solvent
• C. the number of moles of solute dissolved in $1d{m}^3$ of the solvent
• D. the number of moles of solute dissolved in $100ml$ of the solvent

Answer 1

Answer: (A)

We have the definition for molarity as, the number of moles of solute present in one litre of the solution.

$1L=1d{m}^3$

$\therefore$ Molarity $(M)=\frac{\text{ Number of moles of solute }}{\text{ Volume of solution (in L) }}$
