Answer 1

Answer #1

Ans :

To calculate the number of moles of any compound , we divide the mass of sample by the molar mass of the compound.

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

let the mass of compound sample be 100 g

so number of moles will be equal to :

moles = 100 g / 187.56 g/mol

= 0.533 moles
