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 ?

What is the concentration of sugar (C_(12)H_(22)O_(11)) in mol L^(-1)

1.	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 ?
Answer» SOLUTION :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`
