Question

2
Acidic
How many atome of oxygen are presene
in 44 gms of coa at NTP​

Answer 1

Explanation:

Moles of CO

2

=

44

4.4

=0.1 moles

∴ Number of molecules of CO

2

=0.1×6.022×10

23

=6.022×10

22

molecules

But 1 molecule of CO

2

contains 2 oxygen atoms.

∴ Number of oxygen atoms=2×6.022×10

22

=12.044×10

22

atoms

=1.2×10

23
