Web8. The molar mass of H2SO4 is 98.08 g/mol. To calculate the mass of H2SO4 needed to make a 750.0 mL solution with a concentration of 2.00 M, we need to use the formula: mass = moles x molar mass. First, let's calculate the number of moles needed: moles = molarity x volume. moles = 2.00 M x 0.7500 L. moles = 1.50 mol. http://www1.lasalle.edu/~prushan/Potentiometric-lab6.pdf
