34.2 ~g sugar dissolved in 1 8 10² ~g water to from sugar syrup, calculate mole fraction of sugar? (Molar mass sugar =342 , water =18 )

Step-by-step solution

Molar masses of cane sugar and water are 342 ~g / mol and 18 ~g / mol respectively. Number of moles of can sugar = 34.2 ~g 342 ~g / mol =0.1 ~mol Number of moles of water = 180 ~g 18 ~g / mol =10 ~mol Mole fraction of cane sugar = 0.1 0.1+10 =0.0099
