Answer to Problem 57R

The number of moles present in the 469 g of Cu(NO3)2 is 2.5moles .

Explanation of Solution

Given info:

The mass of the copper sulphate is 469 g

The molar mass of the Cu(NO3)2 is MCu(NO3)2=187.56 g/mol

Formula used:

The molar mass formula is calculated as,

  Numberofmoles=massofsubstancemolarmass

Calculation:

By substituting the given values in the above formula, the number of moles can be calculated.

  Numberofmoles=massofsubstancemolarmassNumberofmoles=469 g187.56  g/mol=2.5 mol

Conclusion:

Thus, the number of moles is 2.5moles .
