# At a pressure of #"185 mmHg"# and a temperature of #55^@"C"#, what volume would #2.55xx10^28# molecules of nitrogen gas occupy?

##### 1 Answer

You will need to use the ideal gas law in order to answer this question. The ideal gas law is represented by the following equation::

First there are two conversions that must be made. The temperature in degrees Celsius needs to be converted to Kelvins. This is done by adding 273 to the Celsius temperature:

The number of molecules of nitrogen gas must be converted to moles of nitrogen gas.

Now we're ready to solve the problem.
