The compound 1-iodododecane is a nonvolatile liquid with a density of 1.20g/ml. the density of mercury is 13.6g/ml. what do you predict for the height of a barometer column based on 1-iodododecane, when the atmospheric pressure is 749 torr? what is the pressure, in atmospheres, on the body of a diver if he is 21 ft below the surface of the water when the atmospheric pressure is 742 torr?

a.

b.

Explanation:

Hello,

a.

One could consider the following equation for this exercise's first part:

Whereas is the density, the acceleration of gravity, the height and the atmospheric pressure, thus:

b.

Now, to know the pressure on the diver's body, one uses the following equation considering that the pressure is exerted downwards:

Best regards.

answer; i believe the correct answer is (solid gold);
