3. If we know the volume of a gas sample at STP, we can determine how much mass is present. Assume we have 867L of N2 at STP. What is the mass of the nitrogen gas? (this is a multi step problem - you will have to convert liters to moles, then moles to mass)
Solve and explain.

Hello thereone of the following properties was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version. which property fits this description? answer: atomic mass  was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

08.01 hope this and can i get brainlist? ?

At a given pressure, gas particles with smaller masses move faster.

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
