Answer:
We need 9.045 grams of active ingredient F to prepare a 6.7% (w/w) solution in water.
Step-by-step explanation:
6.7% (w/w) solution in water can also be expressed as: 6.7 g in 100 g of solution.
Hence:
[tex]\frac{6.7g(F)}{100g(solution)}*135 g (solution)=9.045 g(F)[/tex]
We have to dilute 9.045 g of active ingredient F until getting 100 g of solution.
