Which of the following statements about Avogadro’s Law is false? a. One mole of He occupies 22.4 L at STP. b. At constant P and
Ronch [10]

Answer:

The correct answer to the question which  statements about Avogadro’s Law is false is

c. At constant T and P, doubling the moles of gas decreases the volume by half.

Explanation:

Avogadro's law describes the relationship between the volume of a mass of gas and the number of moles present. Avogadro's law states that at standard (or the same) temperature and pressure, equal volumes od all gases contain equal number of molecules

That is mathematically

\frac{V_{1} }{n_{1} }  =  \frac{V_{2} }{n_{2} }  where

V₁ = volume  of first sample

V₂ = volume  of second sample

n₁ = number of moles in first sample

n₂ = number of moles in second sample
