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-
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.
