EXERCISE J (continued) Nan 5. 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)/(m)l )? 6. How many grams of hydrobromic acid are in 100.0 mL of 11.0 M hydrobromic acid solution? 7. A 525.0 mL sample of 5.50 M sulfuric acid has a density of 1.49(g)/(m)L. Express the concentration of the solution in mass percent. 8. Consider the following chemical 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).

On a single toss of a six-sided die, what is the probability of obtaining the following? a number greater than 2 STEP 1: Count the number of ways the event $ E $ can occur. \[ n(E)= \] $ \square $ STEP 2: Count the number of possible outcomes $ \mathscr{U} $. \[ n(\mathscr{U})= \] $ \square $ STEP 3: Give the formula for the probability of event $ E $. (Use $ U $ for $ \mathscr{U} $.) $ \square $ \[ P(E)=\frac{n(\square)}{n(\square)} \] $ \square $ STEP 4: Solve this expression. (Enter your probability as a fraction.) $ \square $
