1. A balloon contains 100g of oxygen gas (O₂) when the volume is 110 dm³. Find the volume of the balloon when the mass of oxygen
igor_vitrenko [27]

The volume of the balloon when the mass of oxygen gas is decreased to 50g is 50L.

We will use the ideal gas equation-

<u>PV=nRT</u>

P=Pressure

V=volume

n=no. of moles

T=temperature

In this question temperature and pressure will remains constant then the above equation can be rewritten as-

V_{1} /n_{1} =V_{2} /n2

where V1= initial volume of the balloon

            V2=  volume of the balloon when the mass of oxygen gas is decreased to 50g

now, substitute the values in the above equation-

  • V1=100dm3=100L
  • n1=100/32=3.12
  • n2=50/32=1.56

       100/3.12=V2/1.56

  • V2=50 L

hence, the volume of the balloon when the mass of oxygen gas is decreased to 50g is 50L.
