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).
But here's what I do know: One mole is a unit of measurement, a number. One mole is equal to 6.02*10^23 of anything. In this case, you have that many O2 molecules. If you have the molar mass of an atom of oxygen, then that is how many grams one mole of that atom weighs.ating Newest Oldest. Best Answer: O2 is a gas and i think it means there is 2 mole of oxygen and its mass would be 32g/mole given you multiply 2*16. whereas if you were asked about oxygen it would only mean one mole of O and its mass would be 16 g/mole.
