Question

How many atoms of Neon are in 65.0 L of Neon gas?

Answer 1

65.0 g NH3 x

mol NH3

17.04 g NH3

x

6.02x1023 NH3 molecules

mol NH3

= 2.30x1024 NH3 molecules

(have uh good day)

Answer 2

mole of Neon = 65L/22.4L

=2.901moles of Neon

1 mole of a substance contains 6.022x10^23atoms

So 2.901moles will contains

2.901 x 6.022x10^23atoms

=1.747 x 10^24atoms
