Question

how much copper can be obtained from 100g of copper sulphate (CuSO4)? [atomic mass of Cu = 63.5]

Answer 1

Given - 
         Atomic mass of Cu = 63.5
         
Now 
       Molar mass of CuSO4
                                    = (63.5) + (32) + 4(16)
                                    =  63.5 +    32 +    64
                                    =  159.5 g

∵1 mole of CuSO4 contains 1 mole of copper.
⇒159.5 g of CuSO4 contains 63.5 g of copper

⇒100 g of CuSO4 will contain of copper = 63.5 *100g / 159.5
                                                                 = 39.81 g
                                                                                   (REQUIRED ANSWER)

Hope it will help u ......

Answer 2

Explanation:

Given - Atomic mass of Cu = 63.5

        

Now ,

 Molar mass of CuSO4 = (63.5) + (32) + 4(16)

                                  =  63.5 +    32 +    64

                                   =  159.5 g

HENCE ,1 mole of CuSO4 contains 1 mole of copper.

⇒159.5 g of CuSO4  contains 63.5 g of copper

⇒100 g of CuSO4 will contain of copper = 63.5 *100g / 159.5

                                                                       = 39.81 g

hope this solution helps you '
