You have a 5-liter container with 1.30×10^24 molecules of ammonia gas (nh3) at stp.

how many molecules of argon gas (ar) are in an identical container at the same temperature and pressure?

a) 6.02×10^24 molecules
b) 1.30×10^24 molecules
c) 2.00×10^23 molecules
d) 6.02×10^23 molecules

The number of molecules of argon gas are

Explanation:

We are given:

Volume of container = 5 L

Number of molecules of ammonia gas =

STP conditions:

The temperature and pressure conditions are 273 K and 1 atm

Also, 1 mole of a gas occupies 22.4 L of gas

As, the conditions of same for argon gas. So, the number of molecules of argon gas will be equal to the number of molecules of ammonia gas.

Hence, the number of molecules of argon gas are
