Answer:
22grams
Explanation:
We use the following formula
n
(
moles
)
=
m
(
mass
)
M
(
molar mass
)
Rearranging this equation, we find that
m
=
n
⋅
M
We are given the moles
(
0.5
)
, so we need to find the molar mass. I'm assuming you are given a table of molar values of elements such as carbon is
12 g/mol
..
So to find moles, we add all the molar values together
M
(
CO
2
)
=
M
(
C
)
+
2
⋅
M
(
O
)
M
(
CO
2
)
=
(
12
+
2
⋅
16
)
g/mol
M
(
CO
2
)
=
44
g/mol
Therefore, we can then use the above-rearranged equation to find
m
:
m
=
0.5 moles
⋅
44 g/mol
m
=
22 g

Answer:
one mole of carbon dioxide weighs 44 g
(12+[2×16] ) =44
then 0.5 mole weighs =44×0.5
= 22.0 g
