A 9.75 L 9.75 L container holds a mixture of two gases at 41 ° C. 41 °C. The partial pressures of gas A and gas B, respectively,

Triss [41]

Answer:

The total pressure P = 1.642 atm

Explanation:

From the dalton's law

Total pressure of the mixture is

$P = P_{A} + P_{B} + P_{C}$ ----- (1)

$P_A = 0.419$ atm

$P_B = 0.589$ atm

$P_C = \frac{nRT}{V}$

n = 0.24 mole

R = $0.0821$ $\frac{L.Atm}{K.mol}$

T = 41 °c = 314 K

$P_C = \frac{(0.24)(0.0821)(314)}{9.75}$

$P_C$ = 0.634 atm

From equation (1)

P = 0.419 + 0.589 + 0.634

P = 1.642 atm

Thus the total pressure P = 1.642 atm

<h3><u>Answer</u>;</h3>

= 226 Liters of oxygen

<h3><u>Explanation</u>;</h3>

We use the equation;

LiClO4 (s) → 2O2 (g) + LiCl, to get the moles of oxygen;

Moles of LiClO4;

(500 g LiClO4) / (106.3916 g LiClO4/mol)

= 4.6996 moles

Moles of oxygen;

But, for every 1 mol LiClO4, two moles of O2 are produced;

= 9.3992 moles of Oxygen

V = nRT / P

= (9.3992 mol) x (8.3144621 L kPa/K mol) x (21 + 273) K / (101.5 kPa)

= 226 L of oxygen
