First, we assume 1000 grams of solvent. This means there are 3.97 moles of sulfuric acid. This is equal to 389.06 grams acid. The total mass of the solution is 1389.06 grams. Using density, the number of liters is 1.142 liters. The molarity in this case is equal to 3.475 molar
hypothetically speaking it's becouse the charges will either could have been lost or not thus since the electron drifted away from the nucleus its energy increases.
