How to Calculate the Molar Mass More Details on the Calculation Definition The molar mass can be defined as the mass of one mole of any substance. As for a mole, that’s just the overall number of atoms in twelve grams of the carbon-12 isotope. That’s always a fixed number, often d...
Calculate the molarity of a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof the solute first. To convert grams to moles, the molar ...
How many grams of water should you add to 35.5 g of sucrose, {eq}C_{12}H_{22}O_{11} {/eq}, to get a 0.720 M solution? Concentration: When you dilute sucrose in water, the molarity is the amount (in moles) of sucrose in the solution per unit ...
