The relative formula mass of CuSO4.5H2O is:
Mr = 63.5 + 32 + 64 + 5(18) = 249.5
So, 249.5 g of CuSO4.5H2O contains 1 mol of substance.
Find the number of moles of substancecontain.
Number of moles =mol.
Now, each mole of substance holds 9 moles of oxygen atoms.
Find the number of moles of oxygen atoms in your amount of moles above.
1 mol --> 9 moles of O
mol
Now, 1 mol means
Find how many doesmol mean.
