A solution of 49.5% H₂SO₄ by mass has a density of 1.39 g/cm³ at 293 K. A 26.0 cm³ sample of this solution is mixed with enough water to increase the volume of the solution to 99.3 cm³. Find the molarity of sulfuric acid in this solution.

The reaction 4 a + c + h → d has the mechanism below. what is the rate law? 1) 2 a → b fast 2) 2 b → b2 fast 3) b2 + c → g slow 4) g + h → d fast a. rate = k[a]2[c] b. rate = k[a]4[h][c] c. rate = k[a]2 d. rate = k[b]2[c] e. rate = k[a]4[c]
