Question

The density of oxygen gas at 293K and 3 atm pressure is?

Answer 1

pV=nRT
n/V=p/RT

Answer 2

@UnkleRhaukus i got n/v = 0.124

Answer 3

then wat to do?

Answer 4

what at the units for n/

Answer 5

n = given mass/molar mass

Answer 6

n is the number of moles

Answer 7

yup

Answer 8

so n = given mass/molar mass

Answer 9

what is the molar mass of oxygen \(O_2\)

Answer 10

32

Answer 11

32 grams / mol

Answer 12

yup i got it it is 4g/l

Answer 13

to get density we want \[\rho=m/V\]mass per unit volume

Answer 14

thxxx for helping!

Answer 15

thats ok.
