As you did above for the gas, now estimate the number of molecules found in a cubic centimeter of a liquid at ordinary pressure and temperature.

There are molecules in a cubic centimeter of water at ordinary pressure and temperature.

Explanation:

Let suppose that liquid is water at a pressure of a atmosphere and a temperature of 25 ºC. Due to incompresibility of liquids, water density does not have any change of importance due to changes in pressure and temperature.

Density and molar mass of water are 1 gram per cubic centimeter and 18.015 grams per mole. The mass of water in a cubic centimeter (), measured in grams, is:

Where:

- Density, measured in grams per cubic meter.

- Volume of the sample, measured in cubic meters.

Given that and , the mass of water is:

The amount of moles () inside the sample is:

Where:

- Mass of the sample, measured in grams.

- Molar mass, measured in grams per mole.

If and , then:

According to the Avogadro's Principle, there are molecules per mole. Hence, the number of molecules in a cubic centimeter of water at ordinary pressure and temperature is determined by simple rule of three:

There are molecules in a cubic centimeter of water at ordinary pressure and temperature.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

the answer would be 32*f
