HOW to find the denstiy of HBr gas (in grams per liter) given temperature and pressure?

What is the density of HBr gas in grams per liter at 733 mmHg and 46 deg. celsius?

Pv=nRT

I converted temp. and pressure

next I did this

.9645atmx81.01g/mol divided by .0821 x 319 K = 78.134145/26.1899 = 2.9833g/L

Is this correct?

    pV = nRT

    n = m / MW

    Therefore pV = (m/MW)RT

    (p x MW)/(RT) = (m/V) = density

    Your answer seems to be correct
