Question

How many oxygen atoms are in 0.100 mol of cuso4 .5h2 o?

Answer 1

Answer:

5.418*10^23

Explanation:

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

0.100 will contain 0.900.

so.

no of oxygen atom= moles of oxygen* 6.02*10^23.

=0.9*6.02*10^23= 5.418*10^23

Answer 2

The number of oxygen atoms in given amount of copper sulfate pentahydrate are $5.42\times 10^{23}$

Explanation:

We are given:

Moles of $CuSO_4.5H_2O$ = 0.100 moles

For 1 mole of copper sulfate pentahydrate, there are 1 mole of copper atom, 1 mole of sulfur atom, 9 moles of oxygen atom and 12 moles of hydrogen atoms

According to mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ number of particles

So, 0.100 moles of copper sulfate pentahydrate will contain = $(9\times 0.100\times 6.022\times 10^{23}=5.42\times 10^{23}$ number of oxygen atoms
