What is the concentration of sugar `(C_(12)H_(22)O_(11))`
in mol `L^(-1)` if its 20g are dissolved in enough water to make a final volume up to 2L ?

Text Solution

Verified by Experts

Molecular mass of sugar `(C_(12)H_(22)O_(11))`
`m = (12xx12.01) + (22xx1.0079) + (11 xx 16.00)`
`= 342.2938 ~=342` g/mole
Weight of solute `= 20g`
Volume of solution `= 2L`
`:.` Molarity `= ("Weight of solute")/("Molecular mass of solution" xx "Volume of solution")`
`=(20)/(342xx2) = 0.0292M`
