A chemical company makes up batches of copper sulfate solution by adding 250 kg of copper sulfate powder to 1000 liters of water. A laboratory chemist wants to make a solution of identical concentration, but only needs 350 mL (0.35 liters) of solution. How much copper sulfate powder should the chemist add to the water?

87.5 grams.

Step-by-step explanation:

Concentration of the company's solution is 250 kg / 1000 liters

= 250 g / liter. (dividing both quantities by 1000).

So the chemist needs 250 * 0.35

= 87.5 g.
