B. V * n

C. V/n

If it takes ‘breaths’ to blow up a balloon to 1.2 L, and each breath supplies the balloon with 0.060 moles of exhaled air, how many moles of air are in 3.0 L balloon?

The Avogadro’s law is one of the most significant gas laws used to portray the conduct of a perfect(ideal) gas, as it relates the volume and number of moles of a perfect gas under steady weight and temperature. The law demonstrates an immediate connection between the quantity of moles and the volume of a perfect gas through the condition
V1/n1=V2/n2
where V1/V2 and n1/n2 are the underlying and last volume/number of moles of the perfect gas, individually.
Avogadro’s law demonstrates a straight proportionality between the volume VV and number of moles nn of a perfect gas. This implies the proportion among the two is steady, or
V/n=k
where k is consistent of proportionality. Thus, the amount that is steady in Avogadro’s law is
C.V/n
The gas, as air from a breath, has the underlying conditions
V1=1.2 L
n1=0.060 moles
