Question

Calculate the number of moles of kool aid powder needed to make 100ml of a 0.1 m solution? 0.1M=x mol C12H22O11/0.1L

Answer 1

(0.100 L) x (0.1 mol/L) = 0.0100 mol

Answer 2

Answer : 0.01 moles

Explanation: Molarity is defined as no of moles of solute dissolved per liter of the solution.

`\text{molarity}=\frac{\text{no of moles of solute}}{\text{volume of solution in litres}}`

`\text{no of moles of solute}={\text{molarity}* {\text{volume of solution in litres}}`

`\text{no of moles of solute} ={0.1m}* {0.1L}`

`=0.01 moles`
