Question

calculate the volume of 220gm of co2 at STP. Also calculate the number of co2 gas molecules in it.
​

Answer 1

Answer:

CaCO

3

+2HCl⟶CaCl

2

+H

2

CO

3

HCl is limiting reagent so the moles of H

=10

−1

mol

Now-

H

2

CO

3

⟶H

2

O+CO

2

n mole of H

2

CO

3

will give same amount of mole for CO

2

The no. of mole of CO

2

=10

−1

mole

The volume of CO

2

-

mole=

22.4

Volume

−1

=

22.4

volume

Volume=2.24L

Answer 2

1 mole of co2=44g

220g=5 moles

no° of molecules =6.022×5×10^23 molecules

1 mole=22.4 l

5 mole=112l

ANS :volume=112l

no bn of molecules=6.022×5×10^23
