Explanation:
(a) Calculate the volumes
One statement of Boyle's Law is, "The pressure
p
exerted by a gas is inversely proportional to the volume if all other factors remain constant".

where

the pressure
k

a proportionality constant
When
V
=
20.0 mL
,
p
=
1.00 atm
,
∴
k
=
p
V
=
20.0 mL × 1.00 atm
=
20.0 mL⋅atm
∴ For this experiment,
p
=
20.0

For example, when
V

,

mL
=
4.0 atm
I calculated the pressures for the other volumes in an Excel table.
