Question

The number of oxygen atoms in 0.6 mole of sodium carbonate is​

Answer 1

Answer:

1 mole of Na

2

CO

3

=106g

moles in 10.6g of Na

2

CO

3

=10.6/106=0.1 mole

106g contain atoms of oxygen =3×6.022×10

23

10.6 contain atoms =0.1×3×6.022×10

23

=1.8×10

23

Answer 2

HELLO DEAR,

GIVEN:-The number of oxygen atoms in 0.6 mole of sodium carbonate is

SOLUTION:- The formula of Sodium Carbonate is Na₂CO₃.

1 mole Na₂CO₃ = 6.022×10²³ molecule of Na₂CO₃.

And in 1 mole Na₂CO₃ no. of oxygen (O) atom is 3×6.022×10²³.

Therefore in 0.6 mole of Na₂CO₃ no. of oxygen atom= 0.6×3×6.022×10²³

= 1.08396×10²³

THANKS.
