Question

What is the mass of 1 mole of O2?
What is the mass of 1 molecule of O2?

Answer 1

Oxygen has a n atomic weight of 16 amu, ergo a mole of O_2 has a mass of 32g, and a molecular weight of 32 amu.

Answer 2

So just 32?

Answer 3

xishem i have a new one for you:D

Answer 4

What is the density of O2 at STP?

Answer 5

And of course STP = volume used, 1 mol any gas = 22.4

Answer 6

d=MM(P/RT) Ideal gas law.

Answer 7

o.O what.

Answer 8

1 mole. of O2 = 32g.
1 mole. at STP occupies 22.4L.
Density = Mass / Volume.
Density of O2 at STP = 32g / 22.4L = 1.43g/L = 1.43kg/m³
