Question

Molarity is defined as:

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

Answer 1

The correct option is A the number of moles of solute present in $1$ $d{m}^3$ volume of solution

Since the molarity is moles per litre and $1{dm}^3$ is equal to $1L.$

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

Hence, the correct answer is option $A$.
