# What is the temperature of a 25.0 g sample of neon gas that exerts a pressure of .922 atm and has a volume of 3.25 L?

##### 1 Answer

#### Answer:

The temperature of the neon sample will be 29.5 K.

#### Explanation:

First convert mass to moles by dividing the given mass of the substance by its molar mass. Then use the ideal gas law to determine its temperature in Kelvins.

**Moles of Neon**

The molar mass of neon is

**Ideal Gas Law**

The equation for the ideal gas law is ** #PV=nRT#**, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvins.

**Unknown**

**Solution**

Rearrange the ideal gas law equation to isolate temperature and substitute the known values into the equation, then solve.
