The meaning of MOLE is a pigmented spot, mark, or small permanent protuberance on the human body; especially : nevus. How to use mole in a sentence.
it isn't necessary thatallmolecules effuse: we just needenoughmolecules to effuse to fulfill the Maxwell-Bolzmann distribution in a meaningful way. For example : if I had 1 mole of a gas at a pressure of 1 bar in A (and "zero" in B), and would allow 10-15mole of this gas to e...

On the second thought - there is a difference between "number of moles of atoms of oxygen in 16g" and "number of moles of molecules of oxygen in 16g", so while in most cases this additional information is not necessary, sometimes it is perfectly in place.Similar...
Mole is the fundamental unit of the amount of substance. The substance can be an element or a compound. All the elements and compounds are made up of particles known as atoms or molecules. Even in a small amount of the substance, these particles are very large in number. Therefore,...
I will give you 8.32 x 10^24 molecules of water How many moles of water have I given you ? Then I tell you that 1 mol of olecules is 6.022*10²³ molecules Now you have no problem : Moles of water = molecules of water / 6.022*10²³ molecules / mol ...
A 0.245-L flask contains 0.467 mol CO2 at 159^oC. Calculate the pressure: (a) Using the ideal gas law (b) Using the van der Waals equation (c) Explain the reason for the difference. (d) Identify which What is the weight in grams of 1 x 10^23 molecules o...
A quantity of oxygen, O 2 , is at a temperature of 70 C and a pressure of one atmosphere. (a) What is the number density of oxygen molecules in this gas? (b) Calculate the temperature of this gas when its pressure increases by three times its initia If a gas...
To go from moles to molecules, multiply the number of moles by 6.02 x 1023. To go from molecules to moles, divide the number of molecules by 6.02 x 1023. For example, if you know there are 3.35 x 1022water molecules in a gram of water and want to find how many moles of water thi...
