A reagent bottle is labeled 0.255 M K2SO4.
(a) How many moles of K2SO4 are present in 25.0 mL of this solution?
(b) How many mL of this solution are required to supply 0.0600 mol of K2SO4?
(c) Assuming no volume change, how many grams of K2SO4 do you need to add to 1.50 L of this solution to obtain a 0.800 M solution of K2SO4?
(d) If 40.0 mL of the original solution are added to enough water to make 135 mL of solution, what is the molarity of the diluted solution?
We need at least 10 more requests to produce the solution.
