HOW MANY OXYGEN ATOMS ARE PRESENT IN 22G OF CO2.??? WITH SOLUTION PLSSSS .... ☺☺☺☺

Answer»

Given

Co2

So in this we have 1 mole of carbon and 2 moles of oxygen

Mass of one mole of carbon = 12

Mass of one mole of oxygen =16

Total mass =12+(16x2)

=12+32

=44G

1 mole of Co2 having 44g mass

Now we are having 22g

So

Dividing it with 2

Then we get half mole of carbon and 1 mole of oxygen

22g=1/2 mole of carbon + 1 mole of oxygen

1 mole of oxygen CONTAINS 6.023 x10²³ atoms of oxygen.

Therefore 22g of Co2 contains 6.023x10²³ atoms of oxygen

This is ur ANS hope it will help you in case of any doubt comment below
