Can any one go through this question please?

A mixture of MgSO4.7H2O and CuSO4.5H2O is heated at 120 C until a mixture anhydrous compounds is produced. If 5.00 g of the mixture gave 3.00 of the anhydrous compounds, calculate the percentage by mass of MgSO4.7H2O in the mixture.

If there is x grams of MgSO₄.7H₂O, how many grams of CuSO₄.5H₂O are there?

How many moles of CuSO₄.5H₂O, and of MgSO₄.7H₂O?

How many moles of CuSO₄ after heating. and of MgSO₄?

What is the mass of CuSO₄ after heating, and of MgSO₄?

I am sorry I am new to chemistry. I have no idea whats going on after heating would be nice if someone did this question for me as I got 10 more which are due tomorrow. So I can use it as an example to carry on with rest.

1. After heating, all H₂O are being removed.

2. So what components remain?
