Question

Calculate the masses of cane sugar and water required to prepare 250 gram of 25% cane sugar solution -

Answer 1

---25% soln means 25% cane sugar and 75% water----
25% cane sugar means in 100gm soln(cane sugar + water) mass of cane sugar is 25gm
by unitary method we have
in 100gm soln 25gm sugar is present
so in 1gm soln 25/100 gm sugar is present i.e. 1/4 gm
hence, in 250 gm soln (1/4 ) * 250 gm sugar is present
or,62.5 gm sugar
so mass of water is 250-62.5=187.5gm
