H:O = 4:5;

(UO₂)₂ = 4 O atoms;
(PO₄)₂ = 8 O atoms:
8H₂O = 16 H atoms + 8 O atoms;

Total = 16 H atoms + 20 O atoms;

H:O = 16:20 = 4:5

Answer:

The ratio by number of H atoms to O atoms is: 4:5

Explanation:

The mineral torbernite, : \(Cu(UO_2)_2(PO_4)2⋅8H_2O\)

Number of oxygen atoms in the mineral :

=\(2\times 2+4\times 2+8\times 1=20\)

Number of hydrogen atoms in the mineral :

=\(8\times 2=16\)

The ratio by number of H atoms to O atoms is:

\(\frac{16}{20}=\frac{4}{5}=4:5\)
