Question

if from 3 moles MgSO4.7H2O all O atoms are takken out and converted into ozone find the number of O3 molecules formed

Answer 1

Answer:

11na

Explanation:

66.243 x 10^23

Answer 2

Given: 3 moles MgSO4.7H2O all O atoms are taken out and converted into ozone.

To find: We have to find the number of ozone formed.

Solution:

The number of oxygen atoms in hepta hydrated magnesium sulfate is 7+4=11.

Thus one mole of $MgSO_4.7H_2O$ has 11 oxygen atoms.

Three moles of $MgSO_4.7H_2O$ will contain 3×11=33 oxygen atoms.

Now one mole of ozone has three oxygen atoms.

33 oxygen atoms will have 33/3=11 mole.

Thus 11N or $11×6.023×10^{23}$ molecules of oxygen atoms will formed.
