Answer: 2.5g

Explanation:

5 % sucrose solution means that 5 % of the weight of the solution is sucrose.

If 1 liter of water weighs 1000 grams. To prepare 5% sucrose solution 5/100 x 1000 = 50 grams. Since 1 liter equals 1000ml, thus a 5 % solution has 50 grams of solute dissolved in one liter.

To prepare 5% sucrose solution in 50mls

=5/100 x 50

= 0.05 x 50

= 2.5g

Therefore to prepare 5% sucrose solution in 50mls we dissolve 2.5g of sucrose in 50ml of water
