Answer:
Adding 15 g of Flubber with 85 g of inert solvent will result in the formation of 15 % solution.
Data Given:
W/V % = 15 %
Weight of Flubber = ?
Weight of Solution = ?
Solution:
Let's suppose we are going to prepare a 100 mL solution. The using following formula we can calsulate the amount of Flubber required.
W / W % = (Weight of Flubber ÷ Weight of Solution) × 100
Putting values,
15 % = (Weight of Flubber ÷ 100 g) × 100
Solving for Weight of flubber,
Weight of Flubber = (15 × 100 g) ÷ 100
Weight of Flubber = 15 g
Hence, taking 15 g of Flubber and adding it to 85 g of solvent will result in the formation of 15% Flubber solution.
