Question

You have a 5-liter container with 1.30×1024 molecules of ammonia gas (NH3) .

How many molecules of hydrogen gas (H2) are in an identical container at the same temperature and pressure?

Responses

2.00×1023 molecules

2.00 times 10 to the power of 23 molecules

6.02×1024 molecules

6.02 times 10 to the power of 24 molecules

6.02×1023 molecules

6.02 times 10 to the power of 23 molecules

1.30×1024 molecules

Answer 1

1.30×10^24 molecules.

Reason: By Avogadro's law (or the ideal-gas law), equal volumes of gas at the same temperature and pressure contain the same number of molecules, regardless of identity.
