Answer 1

34.2 I hope it helps

Answer 2

Answer: The mass of sucrose is 34.23 g

Explanation:

Molarity is defined as the number of moles present in one liter of solution.

Mathematically,

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

Or,

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Molarity of solution = 0.200 M

Molar mass of sucrose = 342.3 g/mol

Volume of solution = 500 mL

Mass of sucrose = ? g

Putting values in above equation, we get:

$0.200mol/L=\frac{\text{Mass of sucrose}\times 1000}{342.3g/mol\times 500mL}\\\\\text{Mass of sucrose}=34.23g$

Hence, the mass of sucrose is 34.23 g
