A mixture of carbon dioxide and krypton gases is maintained in a 8.32 L flask at a pressure of 2.98 atm and a temperature of 71 °C. If the gas mixture contains 20.4 grams of carbon dioxide, the number of grams of krypton in the mixture is 69.11 g.

Answer 1

Valume of flask = 8.322 Total Pressure = 2.98 am Temperature = 12 = 344 K weight of co₂ = 20.4g. no. of mole of co₂ = 20.19 0.464 mod un glmal PVERT 2.98 X 8.32 L = ngx0.082 Lahm k mae x 344K aาวา nr. = 2.98 alm x 8.32 0.082L.amk mool & 344k Total no. of mol of gases = 0.879 mod no. of mole of Kr= n, noe = 0.879 - 0.464 - 0.415 mol mas of Krypton in mixture = 0.415 mal x 83.891000 = 34.78g.
