Question

if the avagadro's number is N, the number of atoms in 2moles of co2 gas is
a)N
b)2N​

Answer 1

Answer:

2 moles of CO2 contain 2×6.023×10^23 no.of molecules.

1 mole carbon dioxide contains 6.02 x 10²³ molecules.

2 mole carbon dioxide contains 2(6.02 x 10²³) molecules.

So it is double of avagadro's number so it became 2N.

(Avagadro's number is N=

6.02214076 × 10²³.)
