9% w/v solution has how many g of active ingredients?
whats the answer and formula.
The formula to calculate this would be:
Mass (g) of active ingredient = 9% x Volume (ml) of solution
Assuming we have 100 ml of solution:
Mass (g) of active ingredient = 9% x 100 ml
Mass (g) of active ingredient = 0.09 x 100 ml
Mass (g) of active ingredient = 9 g
Therefore, a 9% w/v solution of active ingredient would have 9 grams of active ingredient in 100 ml of solution.
