What is ideal gas law?
For an ideal gas(or a gas that behaves sufficiently like an ideal gas), we have the following relation:
[tex]\rm PV = nRT[/tex]
where, the symbol denotes:
- P = Pressure of the gas
- V = volume of the gas
- T = temperature of the gas
- n = count of moles of the gas
- R = universal gas constant = 8314.46261815324 [tex]L.Pa.K^{-1}.mol^{-1}[/tex]
For the given case, the gas in the air mattress has following properties:
P = 3.5 kilopascals =3500 pascals
T =295 K
n = 0.55 moles
V = volume of gas in air mattress = volume of mattress (to evaluate).
Thus, using the ideal gas law, we get:
[tex]V = \dfrac{nRT}{P} = \dfrac{0.55 \times 8314.46261815324 \times 295}{3500} \approx 385.43 \: \rm liters[/tex]
Thus, the volume of the air mattress in liters is 385.43 liters approx.
