Question

2 molar solution will be obtained when 0.5 mole solute is dissolved in

• A. 250 mL solvent
• B. 250 g solvent
• C. 250 mL solution
• D. 1000 mL solvent

Answer 1

The correct option is C 250 mL solution

$M=\frac{\text{moles of solute}}{\text{volume of solution (mL)}}\times 1000$
2 molar solution means 2 M
given moles of solute = 0.5 mole
Volume of solution $=\frac{\text{moles of solute}}{M}\times 1000$
Volume of solution = $\frac{0.5}{2}\times 1000$ = 250 mL of solution
