Answer:
5.33 mol/L.
Explanation:
Its density is 1.3057 g/ml so in a liter (1000 mL) there is 1305.7 g of solution, but only 40% is sulfuric acid.
0.40x1305.7=522.28
So in a liter of 40% sulfuric acid solution there is 522.28 g of sulfuric acid.
Sulfuric acid molar mass iss 98.079 g/mol, so in 522.28 g of sulfuric acid there is
522.28 g /98.079 g/mol=5.33 mol
In one liter of solution there is 5.33 mol of sulfuric acid, so the molarity of such solution is 5.33 mol/L.
