A student performs an experiment where gas is collected over water in an upside down graduated cylinder. If the atmospheric pressure is 745 mmHg and the level of water in the graduated cylinder is 14.4 cm higher than the level of the water exposed to the atmosphere, what is the total pressure of gases inside the graduated cylinder? Enter your answer numerically in units of mmHg.

Respuesta :

Answer:

601mmhg

Explanation:

Pgas = Patm - hρg

Height of water = 14.4cm

Convert to mm

1 cm = 10mm

14.4 cm =

= 14.4cm × 10mm

= 144mm

hpg = 144 mmhg

Ptotal = Patm - hog

= 745mmhg - 144 mmhg

= 601mmhg

The total pressure of gases inside the graduated cylinder = 601mmhg
