Answer: The correct answer is Option a.
Explanation:
To calculate the molarity of solution, we use the equation:
[tex]\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}[/tex]
We are given:
Mass of solute (carbon dioxide) = 44 g
Molar mass of carbon dioxide = 44 g/mol
Volume of solution = 0.5 L
Putting values in above equation, we get:
[tex]\text{Molarity of solution}=\frac{44g}{44g/mol\times 0.5L}\\\\\text{Molarity of solution}=2mol/L[/tex]
Hence, the correct answer is Option a.
