In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
Compounds are weighed using scales to yield grams. It's often necessary to convert grams to moles for chemistry calculations.Peter Muller / Getty Images Learn how to convert the number of grams of a molecule to the number of moles of the molecule with examples below. This type of conversion ...
Step 3: Find how many moles of each ion will be present in 1 liter of the solution at equilibrium if xmolL of the compound dissolves to reach equilibrium. Since 1 mole of Ag2S dissolves into 2 moles of Ag1+ and 1 moles of S2−, xmolL of Ag2S at equilibrium would yield 2xmolL...
Moles of Solute Say you create a solution with 200 grams of table salt. One mole equals the molar mass of the solute which is 58.4538 grams. Divide the mass of the solute by the molar mass to get the number of moles of solute. In this case, work out 200 ÷ 58 = 3.4483 moles of...
Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
