snumber

Givennumberofmolecules

Numberofmoles=

6.022×10

23

1.0505×10

23

Number of moles =0.17

Now, to calculate mass, apply the formula:

Numberofmoles(n)=

Molarmass(M)

Mass(m)

We can write:

Mass (m) = Number of moles (n) × Molar mass of CO

2

(M)

Mass=0.17mol×44g/mol

Mass=7.48g

Thus, the mass of 1.0505×10

23

molecule of CO

2

is 7.48g.
