Question

What is the molar concentration of a solution with 44 grams of CO2 in 0.5 liter solution? a) 2 mole/liter b) 4 mole/liter c) 1 mole/liter d) 3 mole/liter

Answer 1

Answer: The correct answer is Option a.

Step-by-step explanation:

To calculate the molarity of solution, we use the equation:

`\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}* \text{Volume of solution (in L)}}`

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:

`\text{Molarity of solution}=(44g)/(44g/mol* 0.5L)\\\\\text{Molarity of solution}=2mol/L`

Hence, the correct answer is Option a.
