Find the number of gramsof the substance. You will know from the problem how many grams and what the substance is, for example, 12 g of water. Find the molecular weight of each atom in the substance. The molecular weight is how much each molecule of the substance weighs and is given i...
Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
