Question

16. A gas occupies a volume of 2L. at 22°C and 780mm Hg. What volume does it occupy at 100°C and 760mm Hg?

Answer 1

According to combined gas law. - Ti P, initial pressure vt initial volume T → initial temperature in Kelvin Py + final pressure V₂ + final volume Tot final temperature in Kelvin

P = 780 mmHg, V, = 22, = 760 mmHg Vy = ? TI = 22 +223 = 295 x T2 = loot 213= 283 k. (780 mm Hg) (2L) (760mmity) (v2) (295k) (283k) 780 mmH 9 X 22 X 28k (295k) (260 mmHg) q = 1.96913474.
