What is molarity in analytical chemistry?Moles:All elements and compounds have molar masses (for elements) and molecular weights (for compounds). The mass of a substance (in grams) divided by its molecular weight/molar mass is the number of moles....
Originally, a mole was the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's number, which is roughly 6.02x1023. A mole of carbon atoms is 6.02x1023carbon atoms. A mole of chemistry teachers is 6.02x1023...

What is the molar mass of Pb(NO3)2? A hydrate of copper(II) sulfate is 25.5% copper by mass. How many water molecules are there for each unit of copper(II) sulfate? Calculate the molarity (M) of a 15% (w/v) copper sulfate solution (m.w. = 160.0 g/mol). ...
How do you calculate the number of moles in a solution? To calculate the number of moles in a solution given the molarity, wemultiply the molarity by total volume of the solution in liters. How many moles of potassium chloride (KCl) are in 4.0 L of a 0.65 M solution? There are 2.6...
Molar mass is the mass of one mole of a substance. We determine the molar masses from values on the periodic table. Answer and Explanation: Before we can sum all of the molar mass of the elements in acetic acid we need the chemical formula of acetic acid. Acetic acid's chemical formula...
