Question

A flask containing argon gas is connected to a closed-ended mercury manometer. the closed end is under vacuum. if the mercury level in the closed arm is 230. mm above that in the arm connected to the flask, what is the argon pressure, in torr? –230. torr 990. torr 230. torr 790. torr 530. torr

Answer 1

Hey there!:

This is a simple question is you know about your units. The pressure exerted by the argon gas is 230 mmHg. Which is a unit of pressure. 1 Torr is approximately equal to 1 mmHg. So the answer is 230 Torr.

Hope that helps!

Answer 2

The correct answer is option c = 230. torr

Step-by-step explanation:

Hello!

Let's solve this!

First, keep in mind that the conversion from mmHg to torr is:

1mmHg = 1torr

To measure the pressure in a mercury manometer, the height of the mercury is measured and that is the pressure.

In this case, the height is 230mm so the pressure is 230mmHg. Since the conversion is one to one, the answer is 230torr.

Then, we conclude that the correct answer is option c = 230. torr
