What volume does a mixture of \(26.2 \mathrm{g}\) of \(\mathrm{O}_{2}\) and \(35.1 \mathrm{g}\) of \(\mathrm{N}_{2}\) occupy at \(35^{\circ} \mathrm{C}\) and \(755 \mathrm{mm} \mathrm{Hg} ?\)
Given each of the following sets of values for an ideal gas, calculate the unknown quantity. a. \(P=1.01\) atm; \(V=? ; n=0.00831\) mol \(; T=25^{\circ} \mathrm{C}\) b. \(P=? \mathrm{atm} ; V=602 \mathrm{mL} ; n=8.01 \times 10^{-3} \mathrm{mol} ; T=\) \(310 \mathrm{K}\) c. \(P=0.998 \mathrm{atm} ; V=629 \mathrm{mL} ; n=? \mathrm{mol} ; T=35^{\circ} \mathrm{C}\)
Convert the following pressures into pascals. a. \(645 \mathrm{mm} \mathrm{Hg}\) c. 0.876 atm b. 221 kPa d. 32 torr
If \(2.51 \mathrm{g}\) of \(\mathrm{H}_{2}\) is placed in an evacuated \(255-\mathrm{mL}\) container at \(100 .^{\circ} \mathrm{C},\) what will be the pressure inside the container?
Suppose a 24.3-mL sample of helium gas at 25 ^ C and 1.01 atm is heated to \(50 .^{\circ} \mathrm{C}\) and compressed to a volume of \(15.2 \mathrm{mL}\). What will be the pressure of the sample?
