Question

Molarity is

• A. The number of moles of solute present in $1\, dm^3$ 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 $100 \,dm^3$ volume of solution

Answer 1

Answer: (A)

Molarity is defined as the number of moles of solute dissolved in one litre or one $dm ^{3}$ volume of solution. It is expressed by the symbol 'M'

Molarity $(M)=\frac{\text { Number of moles of solute }}{\text { Volume of solution (in } L \text { or } dm ^{3} \text { ) }}$
