Question

We dissolve 2.45 g of sugar in 200.0 g water. what is the mass percent of sugar in the solution?

Answer 1

 The  mass percent  of  sugar  in the   solution is 1.225%

      calculation

mass percent =  [(mass  of solute /mass  of solution ) x  100]

mass   of  solute (  mass of a substance that  dissolve in another substance)

   = 2.45 g

mass  of  solution( mass of a  substance that dissolves  a solute) =200.0 g

Therefore mass  percent = 2.45 g/200.0 g  x 100 = 1.225% of sugar in solution

Answer 2

The fomula on determing the mass percent of a sugar in the solution is simple divide the 2.45 g of sugar in 200 g of water and then multiple by 100.
2.45 / 200 = 0.01225 * 100 = 1.225%
The answer in this question is 1.23% of sugar are need in the solution.
