How many grams of potassium sulfate would be recovered by evaporating 623 mL of 22.5 % potassium sulfate solution to dryness (d = 1.23 g/mL)? How many grams of hydrobromic acid are in 100.0 mL of 11.0 M hydrobromic acid solution?

A 525.0 mL sample of 5.50 M sulfuric acid has a density of 1.49 g/mL. Express the concentration of the solution in mass percent.

Consider the following equation:
sulfuric acid + sodium hydroxide → water + sodium sulfate
A 15.0 mL sample of sulfuric acid required 25.5 mL of 0.546 M sodium hydroxide for neutralization. Calculate the molarity of the acid. (Hint: start by writing and balancing the equation)
