Answer:
482
Explanation:
A cylinder containing 14.68 L of helium gas at a pressure of 169.3 atm is to be used to fill toy balloons to a pressure of 1.071
atm. Each inflated balloon has a volume of 2.429 L. What is the maximum number of balloons that can be inflated? Report your answer to 1 decimal place. (Remember that 14.68 L of helium at 1.071 atm will remain in the exhausted (empty) cylinder)

The answer for the following problem is mentioned below.
- <u><em>Therefore the final moles of the gas is 14.2 × </em></u>
<u><em> moles.</em></u>
Explanation:
Given:
Initial volume () = 230 ml
Final volume () = 860 ml
Initial moles () = 3.8 ×
moles
To find:
Final moles ()
We know;
According to the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of the gas
n represents the no of the moles of the gas
R represents the universal gas constant
T represents the temperature of the gas
So;
V ∝ n
=
where,
() represents the initial volume of the gas
() represents the final volume of the gas
() represents the initial moles of the gas
() represents the final moles of the gas
Substituting the above values;
=
= 14.2 ×
moles
<u><em>Therefore the final moles of the gas is 14.2 × </em></u><u><em> moles.</em></u>
