Question

Calculate the no. of moles present in 1.6 ×10-19 Molecules of CO2 , also find their mass. ​

Answer 1

Explanation:

See as we know,

NO. OF MOLECULES=MOLES×NA[AVOGADRO NUMBER]

So therefore MOLES=MOLECULE/NA

= 1.6×10^-19/6×10^23

=0.26×10^4<--answer for no of mole

Now the Molar mass of CO2=12+16×2=44g

As NO OF MOLES= MASS GIVEN/MOLAR MASS

therefore MASS=MOLES×MOLAR MASS

=0.26×10^4×44

=1.144×10^5<----answer for mass
