Calculate the Mass of CuSO₄ in the Sample

Calculation of CuSO₄ Mass

To calculate the mass of CuSO₄ in the sample, we need to determine the remaining mass after subtracting the masses of mineral oil, sand, and KNO₃ crystals from the total sample mass.

Given data: - Total sample mass = 15.315 g - Mass of mineral oil = 0.879 g - Mass of sand = 6.543 g - Mass of KNO₃ crystals = 4.806 g

Using the formula:

Remaining mass = Total sample mass - mass of mineral oil - mass of sand - mass of KNO₃ crystals

Remaining mass = 15.315 g - 0.879 g - 6.543 g - 4.806 g

Therefore, the mass of CuSO₄ in the sample is 2.087 g.

It is important to properly subtract the masses of the known components to find the mass of CuSO₄ accurately. By following the calculation steps, we can confidently determine the mass of CuSO₄ present in the sample.
