Mammals are largely water. A kilogram of water takes up a liter of volume, so if the moles weigh 4.52×1022 kilograms, they take up about 4.52×1022 liters of volume. You might notice that we’re ignoring the pockets of space between the moles. In a moment, you’ll see why. The cu...
How to Convert Liters to Moles for Liquids Many substances are dissolved in water or other solvents in a laboratory for later use in reactions. These solutions are typically described as “molar solutions.” For example, if you dissolve 1 mol of salt (NaCl) in 1 L of water (H2O), you...

Determine the mass in grams of 30 moles of PbSO_4. A sample of water has a mass of 59.8 grams. How many moles of water are in this sample? What is the mass of 2 moles of HgO? How do you convert milliliters to grams in stoichiometry? How many moles are in 9.8 grams of calcium...
One molar is one mol of solute in a liter of fluid. It is important to notice that the fluid is usually nothing more than a diluting agent. For most of the reactions, the fluid does not participate in any reaction.Concentration times volume is number of mols of the solute material, or...
Given the equation 2Mg + O2 --> 2MgO, how many moles of MgO are produced for every mole of O2 used up? In the acetylene torch, acetylene gas (C_2H_2) burns in oxygen to produce carbon dioxide and water. 2C_2H_2(g)+5O_2(g) \to 4CO_2(g)+2H_2O(g) How ma...
measuringmolesof solute per liter of solution. The concept ofmolaritycan be tough to grasp, but with enough practice, you'll be converting mass to moles in no time. Use this example molarity calculation of a sugarsolutionto practice. The sugar (the solute) is dissolved in water (the ...
