Question

if a sample of cuso4.5h20 contains 3 moles of oxygen molecules then the moles of h atoms are
​

Answer 1

Answer:20/3 moles

Explanation:Sample of CuSO4.5H2O contains 9atoms of Oxygen and 10 atoms of Hydrogen.

Therefore molar ratio=9:10

If this sample contains 3 moles of Oxygen molecules i.e. 6 moles of Oxygen atoms.

Therefore, 6/x=9/10

Therefore x =20/3

Moles of H-atoms is 20/3 .
