Cuantos gramos de sulfato de cobre , disueltos en 25 ml de agua, se necesitan para preparar 100 ml de disolución a 80% en masa

The grams of copper sulfate is 80 g

Explanation:

Given:

25 mL of water

100 mL of solution

80% mass concentration

Question: How many grams of copper sulfate, ms = ?

100 mL of solution to 80% is 80 g of copper sulfate more 20 g of water.

In 25 mL to 80% is 20 g of copper sulfate more 5 g of water.

In conclusion, the grams of copper sulfate is 80 g

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
