You have a 5-liter container with 1.30 × 1024 molecules of ammonia gas (NH3) at STP. How many molecules of hydrogen gas (h2) are in an identical container at the same temperature and pressure?

(Points: 3)

6.02 × 1023 molecules <-

1.30 × 1024 molecules

2.00 × 1023 molecules

    ideal gas law

    .. PV = nRT

    .. n = PV/(RT)

    for 2 gases

    .. n1 = P1V1/(RT1)

    .. n2 = P2V2/(RT2)

    if P1=P2 and V1=V2 and T1=T2

    then n1 = n2

    "c" is the correct choice

    1.30 × 10^24 molecules

    If the volume, temperature, and pressure are all equal, there must be an equal number of moles, which means an equal number of molecules.
