Determining the volume of water displaced by the crown and using the gold density to determine the mass of the crown equals the mass got from weighing the crown on a weighing machine. if the mass matches the mass got from the weighing machine then the crown is made of pure gold if otherwise, the gold is not pure.

A chemist dissolves 581.1mg of pure perchloric acid in enough water to make up 150 ml of solution. Calculate the pH of the solut
algol [13]

<u>Answer:</u> The pH of the solution is 1.41

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

Given mass of perchloric acid = 581.1 mg = 0.5811 g   (Conversion factor:  1 g = 1000 mg)

Molar mass of perchloric acid = 100.5 g/mol

Volume of solution = 150 mL

Putting values in above equation, we get:

\text{Molarity of perchloric acid}=\frac{0.5811\times 1000}{100.5\times 150}\\\\\text{Molarity of perchloric acid}=0.0385M

1 mole of perchloric acid produces 1 mole of H^+ ions and 1 mole of ClO_4^- ions

To calculate the pH of the solution, we use the equation:

pH=-\log[H^+]

We are given:

[H^+]=0.0385M

Putting values in above equation, we get:

pH=-\log (0.0385)=1.41

Hence, the pH of the solution is 1.41
