For this task we use the Dalton’s law which says that total pressure of mixture of gases equals to the sum of partial pressures of individual gases: Ptotal=PA+PB+PC+PD Therefore PD = Ptotal – PA – PB – PC. Do the calculation: PD = 860 – 220 – 220 – 110 = 310 mmHg. Answer: The pressure is exerted by gas D is 310 mmHg

What is the total pressure of a mixture containing two gases if the partial pressure of one gas is 70 torr and the partial pressure of the other gas is 30 torr?

P1 = 70 torr , P2 = 30 torrPTotal = P1 + P2 PTotal = 70 torr + 30 torr = 100 torr

The partial pressure of gas X is 340 mm Hg. The partial pressure of gas Y is 264 mm Hg. The partial pressure of gas Z is 100 torr. What is the total pressure exerted by the gases in this system?

According to Dalton's Law of Partial Pressure;Pt= Px +Py+ Pz = (340+264+100)mmHg (since 1torr=1mmHg) = 704mmHg

A gas exerts a pressure of 2.0 atm, at 30°C, in a 10 L container. In what size container would the same amount of gas exert a pressure of 4.0 atm at 20° C?

Using the gas law: pV = nRT, and keeping the same number of moles of gas (n),we find the final volume V2:V2 = (T2/p2)*(p1*V1/T1) = (293 K/ 4.0 atm)*(2.0 atm...

The partial pressure of Ch4(g) is 0.145 atm and that of O2(g) is 0.200 atm in a mixture of the two gases. What is the mole fraction of each gas in the mixture?

p_i/p_total =x_i=n_i/n_total , where x_i- mole fraction. x_(〖CH〗_4 )= (0.145 atm)/((0.145+0.200) atm)×100%=42.0%; x_(O_2 )=(0.200 atm)/((0.145+0.200) atm)×100%=58.0%. Answer: x_(〖CH〗_4 )=42.0%; x_(O_2 )=58.0%.

A 19.5L flask at 15°C contains a mixture of three gases: N2 (2.50mol), He (0.38mol), and Ne (1.34mol). Calculate the partial pressure of neon gas in the mixture.

Total mole of gas= 4.22 molePV = nRT19.5L×P = 4.22×0.08205746 L atm/k×(15+273)kOr, P =5.11 atmPertial pressure of neon =( 1.34/ total mole)×P=(1.34/4.22)*5.11=1.62 atm

A mixture of gases contains 0.31 mol CH4, 0.25 mol C2H6, and 0.29 mol C3H8. The total pressure is 1.50 atm. Calculate the partial pressures of the gases.

p(CH4) = 0.55 atmp(C2H6) = 0.44 atmp(C3H8)= 0.51 atm
