A certain ideal gas has atomic mass number 806. A flask of volume 0.0996 m3 holds this gas under pressure 8.36x105 Pa and temperature 304 K.

How many molecules are in the flask? Give your answer is scientific notation.

Homework Answers

Answer #1

We know ideal gas equation is given By:

Where

  • P is pressure of gas
  • Volume of gas
  • n=number of moles of gas.
  • T is Temperature of gas
  • R is Gas constant =8.314 J/mol-K

Putting the Given values in the above equation we have:

Thus number of moles of gas is (n):

Also we know Number of particle N is:

Where is Avgadro number.

Or,

Or there are 1.98x10^25 molecules in the flask.
