If 2.38 mol of a gas has a volume of 120.0 mL, what is the volume of 1.97 mol of the gas at the same temperature and pressure?

Gwar [14]

According to the Avogadro's law, equal volumes of all gases contain equal number of moles under the same conditions of temperature and pressure.

Here the initial volume, $V_{1} = 120.0 mL$

Initial moles of the gas, $n_{1}=2.38 mol$

Final volume of the gas $V_{2} = ?$

Final moles of the gas $n_{2}= 1.97 mol$

Plugging in the Avogadro's equation,

$\frac{V_{1}}{n_{1}} = \frac{V_{2}}{n_{2}}$

$\frac{120.0 mL}{2.38 mol} = \frac{V_{2}}{1.97 mol}$

$V_{2} = 99.33 mL$

Therefore the 1.97 mol of the gas occupies 99.33 mL at constant temperature and pressure.

The state of water is determined solely by the conditions of _____.

Elenna [48]

<h3>Answer:</h3>

The state of water is determined solely by the conditions of <u>pressure and temperature</u>.

<h3>Explanation:</h3>

Effect of Temperature:

Temperature has direct effect on the kinetic energy of water molecules. Greater the Temperature greater is the K.E of molecules and lesser is the intermolecular forces between molecules. Therefore, at temperature below 0 °C water exists in solid state, at temperature in between 0 and 100 °C it exists in liquid state and (at sea level) and above 100 °C it exists in vapor state.

Effect of Pressure:

The state of water is also influenced by the external pressure. For example, water can be converted into gas phase by reducing the external pressure (this technique is used in vacuum distillation where solvents are evaporated at temperatures lower than their boiling points) and also, the water can remain in liquid state even above 100 °C if the external pressure is increases (this method is being utilized in daily use pressure cookers).
