Question

What mass of H₂SO₄ would be required to prepare 850 mL of a 0.18M H₂SO₄ solution?

Answer 1

Take the 850 mL and divide by 1000 to get the volume in liters. Multiply 0.850 L by. 18 mol/L to get mol H2SO4. Calculate the molar mass of H2SO4 by adding together 2 hydrogens, a sulfur, and four oxygens. Multiply the number of moles by the molar mass to get your answer. Remember to round to 2 significant figures since the molarity is least precise.
