(4 أل containing The density of concentrated ammonia, which is 28.0% w/w NH3, is 0.899 g/mL. What volume of this reagent should be diluted to 1.0 x10³ mL to make a solution that is 0.036 M in NH3? nous solution contains 45.1 mg of a pesticide. Express the

A lab requires 200.0 mL of 0.352 M H2SO4. The only solution available is 9.55 M H2SO4. (a) How many mL of the 9.55M H2SO4 solution will you need? (b) How many mL of water will you need?

For this question it’s telling me use KCI which stands for potassium chloride so do I use KCl, (1 atom X 39.0983 Potassium) + (1 atom X 35.453 Chlorine) = (74.5513 g/mol) and use that with 10 ML of 20% Solution. I’ve been stuck on figuring out what I could do for this question. I want a long clarification and steps on it so it could help me know if I’m correct as I’m doing this question on my notebook.
