Discuss why equal masses of carbon atoms and oxygen atoms don't contain the same number of particles?Mass vs Mole:There are two fundamental units for quantifying substances and their distinction is important. One is Mass which is a measure of the inertia of ...
How many moles are equal to 3.25×1024 atoms of mercury? Avogadro Number:A constant number that illustrates the number of particles existing in the unit mole of the material is known as the Avogadro number. The unit to describe the Avogadro number is atoms per mole....
of oxygen atoms in a given mole of water, we use 1 mole of O_2 atoms/1 mole of H_2O. Why? Atomic mass of Cu is 63.6 amu. Calculate the mass of 3.5 moles of Cu. How to get the molar mass of a compound Calculate the number of moles of the compound C4H9...
The standard molar entropies at 25 ^oC for hydrogen gas, oxygen gas, and liquid water are, respectively 130.68, 205.14, and 69.91 J K^{-1} mol^{-1}. What is the standard entropy change at 25 ^oC for the formation of liquid water from its ...
