Question

Number of molecules in 100 ml of each of Oz, NH, and CO, at STP are :
(A) In the order Co2, <02, <NH3,
In the order NH3, <02, <CO3,
(C)
(D) NH3 = CO2, < 02
The same​

Answer 1

ANSWER

According to Avogadro's law, at the same temperature and pressure condition, an equal volume of all gases have the same number of molecules. Avogadro's law is defined as the volume of gas is directly proportional to the number of moles of gas.where,

V = volume of gas

n = number of moles of gas

As per the question, the volume of each gas is equal at STP.

Therefore, the number of molecules in 100 ml of each of gas at STP are the same.

Hence, the correct option is C
