Aflask 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

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!

The correct answer is option c = 230. torr

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

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
