Question

how many oxygen atoms are in 0.100 mol of cuso4 5h20

Answer 1

Answer:

1 mole of CuSO4. 5H2O contain 9 moles of oxygen atom. 0.100 will contain 0.900.

Answer 2

The number of oxygen atoms is 5.42 ×$10^{23}$

Given,

CuSO4.5H2O Copper Sulfate Pentahydrate.

To Find,

The number of atoms in 0.100mol of CuSO4.5H2O.

Solution,

Given that Copper sulfate pentahydrate and the need to find the number of oxygen atoms.

In CuSO4.5H2O, there is a total of 9 atoms of oxygen.

4from the copper sulfate.

5 oxygen atoms are present in the water molecule.

Based on the mole concepts 6.022×$10^{23}$ particles are there in one mole of compound.

So, in 0.100mol of CuSO4.5H2O contains = 9 × 0.100 × 6.022 ×$10^{23}$

The Oxygen atoms number =  5.42 ×$10^{23}$.

Hence, 5.42 × $10^{23}$ oxygen atoms are present in 0.100mol of CuSO4.5H2O.
