Calculate the density of the rock if its mass is 360 g.
Pavel [41]

Answer:

12.0 g/mL

Explanation:

From the question given above, the following data were obtained:

Mass of Rock = 360 g

Volume of water = 150 mL

Volume of water + Rock = 180 mL

Density of Rock =?

Next, we shall determine the volume of the rock. This can be obtained as follow:

Volume of water = 150 mL

Volume of water + Rock = 180 mL

Volume of Rock =?

Volume of Rock = (Volume of water + Rock) – (Volume of water)

Volume of Rock = 180 – 150

Volume of Rock = 30 mL

Finally, we shall determine the density of the rock as illustrated below:

Mass of Rock = 360 g

Volume of Rock = 30 mL

Density of Rock =?

Density = mass /volume

Density of Rock = 360 / 30

Density of Rock = 12.0 g/mL

Thus, the density of the rock is 12.0 g/mL

Answer:

a hydrogen bond between the hydrogen of water and the nitrogen of the amine

a hydrogen bond between the oxygen of water and a hydrogen from the -NH2 group

Explanation:

A hydrogen bond is formed between molecules in which hydrogen is bonded to a highly electronegative element.

In amines, hydrogen is bonded to nitrogen while in water, hydrogen is bonded to oxygen. Both are highly electronegative elements hence hydrogen bonding is possible between amines and water.

This hydrogen bond may involve;

The hydrogen of water and the nitrogen of the amine

Or

The oxygen of water and a hydrogen from the -NH2 group
