Ideel Gas law 8. Find the emperature of 4 moles of gas with a volume of \( 2 L \) and a pressure of \( 3 \mathrm{~atm} \). (4) Calculate the pressure of 6 moles in gas at a rolume of \( 5 \mathrm{~L} \) and a temperature of \( 300 \mathrm{~K} \). Combined Gas law (5.) Helium gas has a volume of \( 250 \mathrm{ml}^{\mathrm{L}} \) at \( \mathrm{D}^{\prime} \mathrm{C} \) at 1 atm. What will be the final prossuro if the volumo is reduced to \( 100 \mathrm{~mL} \) at \( 45^{\circ} \mathrm{C} \) ?

Step 1
For the first part, we are given: n = 4 moles V = 2 L P = 3 atm We need to find T. Rearranging the equation, we have: T = PV / (nR) Substituting the given values, we get: T = (3 atm) * (2 L) / (4 moles * R) Since R is a constant, we can use the value 0.0821 Show more…

Calculate each of the following quantities for an ideal gas: (a) the volume of the gas, in liters, if 1.50 mol has a pressure of 1.25 atm at a temperature of $-6^{\circ} \mathrm{C} ; \mathbf{b}$ ) the absolute temperature of the gas at which $3.33 \times 10^{-3}$ mol occupies 478 $\mathrm{mL}$ at 750 torr; (c) the pressure, in atmospheres, if 0.00245 $\mathrm{mol}$ occupies 413 $\mathrm{mL}$ at $138^{\circ} \mathrm{C} ;(\mathbf{d})$ the quantity of gas, in moles, if 126.5 $\mathrm{L}$ at $54^{\circ} \mathrm{C}$ has a pressure of 11.25 $\mathrm{kPa}$ .
A gas exerts a pressure of 3 kPa on the walls of a container. When the gas is emptied into a 10-litre container, the pressure exerted by the gas increases to 6 kPa. Find the volume of the original container. Assume that the temperature and quantity of the gas remain constant. (Boyle's Law)
