Dilated pupils: Introduction. Dilated pupils occur when the pupils of the eyes increase in size. The pupils are commonly known as the round, black centers of the eyes. Dilation of the pupils is a normal response to low levels of light or darkness.This response helps a person to see better in situations of low light.ilated pupils: Introduction.

Eric Muller â Exploratorium Teacher Institute 2005 A Mole of Gas 22.4 liters of gas!22.4 liters of gas is the volume of 1 mole of gas at STP(Standard Temperature and Pressure = 0 degrees C at 1ATM).Hereâs a couple of ways to see what 6.02x10 23 of gas molecules lookslike.ric Muller â Exploratorium Teacher Institute 2005 A Mole of Gas 22.4 liters of gas!22.4 liters of gas is the volume of 1 mole of gas at STP(Standard Temperature and Pressure = 0 degrees C at 1ATM).
To find the number of molecules in a gas sample, given the pressure, volume, and temperature of the sample: 1  Figure out how many moles of CO 2 gas you have.2  Use Avogadro's number to convert moles into molecules: 0.0211915 mol Ã 6.02Ã1023 molecules/mol = 1.28 Ã 1022 molecules. Convert molecules of gas to moles of gas, using the mole-to-molecule conversion. 2  Assuming the gas sample is ideal, you can easily compute the volume of the gas using the ideal gas equation of state because you know the temperature, pressure, and moles of gas.
