The density of liquid mercury is 13.6 g/mL. What is the mass of a 175 mL sample of mercury?

The answer is

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

density of mercury = 13.6 g/mL

volume = 175 mL

The mass of the metal is

mass = 13.6 × 175

We have the final answer as

Hope this helps you

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
