If the concentration of a saturated solution at 0∘c is 12.5 gcuso4/100 g soln, what mass of cuso4⋅5h2o would be obtained? [hint: note that the solution composition is stated in terms of cuso4 and that the solid that crystallizes is the hydrate cuso4⋅5h2o.]

Mass of CuSO4.H2O obtained:

Explanation:

The molecular weight of the salt is:

In the solution: 12.5 g of CuSO4

In moles:

Mass of water:

5 moles of water per mol of salt:

Mass of CuSO4.H2O obtained:

what's the

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
