How to solve molarity steps
WebMar 6, 2014 · The molarity becomes the [H+] concentration of 3.2 × 10−3. We know this is the [H+] concentration because HNO3 is a strong acid, since the acid will completely dissociate into H+ and NO− 3. To find the pH calculate −log[H+] −log[3.2 × 10−3] = 2.49 = pH To find the pOH take the pH value and subtract it from 14. 14 −2.49 = 11.51 = pOH WebOct 2, 2024 · To calculate molarity: Find the number of moles of solute dissolved in solution, Find the volume of solution in liters, and Divide moles solute by liters solution.

WebSome chemists and analysts prefer to work in acid concentration units of Molarity (moles/liter). To calculate the molarity of a 70 wt. % nitric acid the number of moles of HNO 3 present in 1 liter of acid needs to be calculated. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413 WebStep 2. Find the total mass of the solution. Multiply 1 L X the density (1.54 g/mL) X 1000 mL/L. This gives 1540 grams of solution. Step 3. Calculate the grams of the solute. 2.5M means 2.5 moles of sulfuric acid per one liter of solution. Convert 2.5 moles to grams.
