Question

A chemist adds of a aluminum chloride solution to a reaction flask. Calculate the mass in grams of aluminum chloride the chemist has added to the flask. Round your answer to significant digits.

Answer 1

Answer:

10.8 g

Explanation:

A chemist adds 480.0 mL of a 0.169 mol/L aluminum chloride solution to a reaction flask. Calculate the mass in grams of aluminum chloride the chemist has added to the flask. Round your answer to 3 significant digits.

Step 1: Given data

• Volume of the solution: 480.0 mL

• Concentration of the aluminum chloride solution: 0.169 mol/L

Step 2: Calculate the moles of aluminum chloride in the solution

We will multiply the volume of the solution by the molarity.

0.4800 L × 0.169 mol/L = 0.0811 mol

Step 3: Calculate the mass corresponding to 0.0811 moles of AlCl₃

The molar mass of AlCl₃ is 133.34 g/mol.

0.0811 mol × 133.34 g/mol = 10.8 g
