## Homework Statement

Calculate the density of Oxygen at STP using the ideal gas law

## Homework Equations

PV=nRT

## The Attempt at a Solution

n = (X grams Oxygen / 16g/mol Oxygen)

I set V = to 1 m3

P = 1 atm

R = 8.315 J/Mol K

T = 273 K

PV = nRT

PV/RT = n

1/(8.315*273) = X grams Oxygen / 16g/mol Oxygen

[1/(8.315*273)]*16 = X grams Oxygen

X = .007g/m3

Book answer is 1.43 kg/m3. I'm way off somewhere.

Thanks for any help!
