Two sealed flasks each have a volume of 2.0 liters. Flask A contains N, O gas and Flask B contains H, gas both at 1

STP. Each gas has the same -

Each gas have same number of molecules.

Explanation:

According to Avogadro law,

Equal volume of all the gases at same temperature and pressure have equal number of molecules.

Mathematical expression:

V ∝ n

V = Kn

V/n = K

k = constant

V = volume of gas

n = number of moles of gas

when volume change is changed from v1 to v2 and number of moles from n1 to n2 this law can be written as,

V1 / n1 = V2 / n2

This state that by increasing the number of moles of gas volume also goes to increase.
