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.

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
