Question

How many
moles are in 4.4g of CO2?
(MOLAR MASS OF CO2=44u​

Answer 1

Answer:

one mole of carbon,

1

×

C

two moles of oxygen,

2

×

O

Oxygen has a molar mass of

16.0 g mol

−

1

, so

1

mole of oxygen atoms has a mass of

16.0 g

.

This means that if you take

44.01 g

of carbon dioxide, you know for a fact that it will contain

2

moles O

⋅

16.0 g

1

mole O

=

32.0 g O

This means that

100 g

of carbon dioxide will contain

100

g CO

2

⋅

32.0 g O

44.01

g CO

2

=

72.7 g O
