214.2 g of sugar syrup contains 34.2 g of sugar. Calculate (i) molarity of the solution and (ii)mole fraction of sugar in the syrup.
Step 1: Given Data
Mass of sugar =
Mass of solution =
Step 2: Formula used
The number of moles of sugar can be represented by the formula = .
Step 3: Calculating the Mass of water
Step 4: Calculating the Number of moles in the water
(molar mass = 18 )
Step 5: Finding Molarity
Molarity = Number of moles of sugar/Mass of water per Kg
Step 6: Formula used
Step 7: Calculating the Total number of moles of sugar syrup
number of moles of sugar syrup
=
Hence, the molarity of sugar is, the mole fraction of sugar syrup is .
