Question
A flask has a volume of $5.0 \times 10^{-4} \mathrm{m}^{3}$ and contains air at a temperature of $300 \mathrm{K}$ and a pressure of $150 \mathrm{kPa}$(a) Find the number of moles of air in the flask.(b) Find the number of molecules in the flask.(c) Find the mass of air in the flask. You may take the molar mass of air to be $29 \mathrm{g} \mathrm{mol}^{-1}$.
Step 1
0 \times 10^{-4} \mathrm{m}^{3}$, the temperature (T) as $300 \mathrm{K}$, and the pressure (P) as $150 \mathrm{kPa}$ which is equal to $150 \times 10^{3} \mathrm{Pa}$. Show more…

(a) Find the number of molecules in $1.00 \mathrm{~m}^{3}$ of air at $20.0^{\circ} \mathrm{C}$ and at a pressure of $1.00 \mathrm{~atm} .(b)$ What is the mass of this volume of air? Assume that $75 \%$ of the molecules are nitrogen $\left(\mathrm{N}_{2}\right)$ and $25 \%$ are oxygen $\left(\mathrm{O}_{2}\right)$.
A $3800-\mathrm{mL}$. flask is initially open in a room containing air at $1.00$ atm and $20^{\circ} \mathrm{C}$. The flask is then closed and immersed in boiling water. When the air in the flask has reached thermodynamic equilibrium, the flask is opened, and air is allowed to excape. The flask is then closed and cooled back to $20^{\circ} \mathrm{C}$. Find (a) the maximum pressure reached in the flask, (b) the number of moles that escape when air is released, and (c) the final pressure in the flask.
At $0^{\circ} \mathrm{C}$ a $1.0-\mathrm{L}$ flask contains $5.0 \times 10^{-2}$ mole of $\mathrm{N}_{2}, 1.5 \times$ $10^{2} \mathrm{mg} \mathrm{O}_{2},$ and $5.0 \times 10^{21}$ molecules of $\mathrm{NH}_{3} .$ What is the partial pressure of each gas, and what is the total pressure in the flask?
