WebProblem #2: What is the molarity of 245.0 g of H 2 SO 4 dissolved in 1.000 L of solution? Solution: MV = grams / molar mass (x) (1.000 L) = 245.0 g / 98.0768 g mol¯ 1. x = 2.49804235 M to four sig figs, 2.498 M If the volume had been specified as 1.00 L (as it often is in problems like this), the answer would have been 2.50 M, NOT 2.5 M.
