Explanation:
We were given
2.6
×
10
23
molecules of
SO
2
. That means that
N
=
2.6
×
10
23
molecules
Use
n
(
number of moles
)
=
N
N
A
(
Avogadro's constant
)
to get
n
=
2.6
×
10
23
molecules
6.02
×
10
23
molecules/mol
=
0.432 moles
Now use
m
=
n
×
M
(
molar mass
)
to get
m
=
0.432 mol
×
64.066 g/mol
=
27.677 g
So
m
(
in kilograms
)
=
27.677 g
10
3
g/kg
=
0.028 kg
