## anonymous one year ago A sample of oxygen gas (O2) has a temperature of 273 K at 1.00 atm. What should the density of this gas be

1. Astrophysics

$\rho = \frac{ mass }{ volume }$ where $\rho = density$ $P=1 atm = 101 kPa$\ $T = 273K$

2. Astrophysics

So we can find the molar mass of oxygen $M_{O_2} = 32 \frac{ g }{ mol }$ are you given more information?

3. UnkleRhaukus

Use $PV=nRT$and $n = m/M$

4. JFraser

as @unklerhaukus says, use the ideal gas law and rearrange it to solve for $$\frac{mass}{volume}$$
