To understand how the mole is related to mass, volume, and the number of molecules of a substance, we can break it down into three parts:(i) Mole and Mass 1. Definition of a Mole: A mole is a unit that measures
Use molar volume to solve the following at STP: The volume (mL) occupied by 0.420 mol of He. How many liters of solution are needed to make a 1.66 M solution containing 2.11 moles of KMnO4? How many mL of water must be added to 500.0 mL of methanol (CH_4O) ...
Calculate the solubility of the compound in moles per liter. Ignore any acid-base properties. AgCl, Ksp = 1.6 times 10-10 mol/L The Ksp of AgCl is 1.6 x 10-10. What is the solubility of AgCl in 0.010 M CaCl2? Give your answer using scientific ...
Molar mass is also known as the atomic mass or molecular weight. The calculation formula of the molar mass can be written as the ratio of compound mass to the number of mole of the compound, and the obtained unit is gram per mole....
