Final answer:
To find the concentration (mass percent) of MgSO4 in the mixture, we can use the given information about the mass of BaSO4 precipitated. By calculating the mass of MgSO4, we can then determine the concentration (mass percent) of MgSO4 in the mixture.
Step-by-step explanation:
To find the concentration (mass percent) of MgSO4 in the mixture, we can use the given information about the mass of BaSO4 precipitated. The mass of MgSO4 can be calculated using the molar mass ratio between BaSO4 and MgSO4.
First, we need to find the molar mass of BaSO4. The molar mass of BaSO4 is 233.43 g/mol. Then, we can use the following equation:
Mass of MgSO4 = Mass of BaSO4 x (1 mol BaSO4 / 233.43 g BaSO4)
Using the given mass of 0.6168 g of BaSO4, we can calculate the mass of MgSO4. Finally, we can find the concentration (mass percent) of MgSO4 in the mixture using the mass of MgSO4 and the total mass of the mixture.
