Question

What is the density of carbon monoxide gas, `CO`, at STP?

Answer 1

We use the molar volume of an ideal gas at `STP` to give `rho_(CO)~=1.2*g*L^-1`

Explanation:

At `STP`, the molar volume of an Ideal Gas `=` `22.414*L*mol^-1`.

Now `rho, "density"="Mass"/"Volume"` `=` `(28.0*g)/(22.414*L)` `=` `??`
