If 0.336 grams of potassium chloride is produced in the following reaction, how many moles of oxygen are also produced? KClO3 arrow KCl + O2 How many moles of KCl are formed when 45.7 grams of KClO3 completely decompose? ...
How many moles of NH3 are there in a 12.50gram sample? Number of Moles of Sample: When the total molar mass of a substance from a table of standard values is represented as M, then we'll divide the number of grams by this value for the total number of moles of the sample. Answ...
moles of water in one drop = 0.002775 moles Using Avogrado's Number Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there...
