Question

Calculate the volume in millimeters of a 0.881 mol/l aluminum chloride solution that contains 75.0 g of aluminum chloride

Answer 1

To calculate the volume of the aluminum chloride solution, follow these steps: Calculate the number of moles of aluminum chloride. Use the given molarity and moles to calculate the volume in liters. Convert the volume from liters to millimeters.

Step-by-step explanation:

To calculate the volume of the aluminum chloride solution, we can use the formula:

1. Calculate the number of moles of aluminum chloride using the given mass of the compound and its molar mass.
2. Use the given molarity and the number of moles of aluminum chloride to calculate the volume of the solution in liters.
3. Convert the volume from liters to millimeters by multiplying by 1000.

In this case, we have 75.0 g of aluminum chloride, which has a molar mass of 133.34 g/mol. So, the number of moles of aluminum chloride is:

0.881 mol/L * 75.0 g / 133.34 g/mol = 0.494 mol

Next, we can use the molarity and number of moles to calculate the volume:

Volume = moles / molarity = 0.494 mol / 0.881 mol/L = 0.56 L

Finally, we can convert the volume from liters to millimeters:

Volume = 0.56 L * 1000 mL/L = 560 mL
