Type the correct answer in the box. Express your answer to three significant figures. An air mattress is filled with 0. 55 moles

The volume of the air mattress in liters is 385.43 liters approx.

<h3>What is ideal gas law?</h3>

For an ideal gas(or a gas that behaves sufficiently like an ideal gas), we have the following relation:

\rm PV = nRT

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 L.Pa.K^{-1}.mol^{-1}

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:

V = \dfrac{nRT}{P} = \dfrac{0.55 \times 8314.46261815324 \times 295}{3500} \approx 385.43 \: \rm liters

Thus, the volume of the air mattress in liters is 385.43 liters approx.
