QUESTION:
Calculate the density of hydrogen bromide (HBr) gas in grams per liter at 733 mmHg and \(46^{\circ} \mathrm{C}\).
ANSWER:Step 1 of 2
The goal of the problem is to calculate the density of hydrogen bromide (HBr) gas in grams per liter at 733 mmHg and \(46^{\circ} \mathrm{C}\).
Given:
\(\begin{array}{l}
T=46^{\circ} \mathrm{C}=46+273=319 \mathrm{~K} \\
P=733 \ \mathrm{mmHg} \\
d=?
\end{array}\)
The formula to find molar mass can be used to find the density of gas:
\(\mathrm{M}=\frac{d R T}{P}\)
This can be rewritten as:
\(\mathrm{d}=\frac{P M}{R T}\)
R = gas constant = 0.0821 L.atm mol-1 K-1
