Question

Avogadro’s law states that the volume (V) and number of moles (n) are directly proportional if the pressure and temperature both remain constant.
How is this written in equation form?

Answer 1

Answer: $\frac{V_1}{V_2}=\frac{n_1}{n_2}$

Explanation:

According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,

$V\propto n$

or,

$\frac{V_1}{V_2}=\frac{n_1}{n_2}$

where,

$V_1$ = initial volume of gas

$V_2$ = final volume of gas

$n_1$ = initial moles of gas

$n_2$ = final moles of gas
