To determine the amount of copper sulfate CuSO4 present in a 5.00 grams sample using gravimetric analysis, we need to know the percentage composition of copper sulfate in the compound.1. Calculate the molar mass of copper sulfate CuSO4 :Cu: 63.55 g/molS: 32.07 g/molO: 16.00 g/mol x 4 = 64.00 g/mol Molar mass of CuSO4 = 63.55 + 32.07 + 64.00 = 159.62 g/mol2. Calculate the percentage composition of copper sulfate in the compound:Let's assume the compound contains 100% copper sulfate since it's the only component mentioned . Therefore, the percentage composition of CuSO4 in the compound is 100%.3. Calculate the amount of copper sulfate in the 5.00 grams sample:Amount of CuSO4 = Percentage composition of CuSO4 / 100 mass of the sampleAmount of CuSO4 = 100 / 100 5.00 grams = 5.00 gramsSo, there are 5.00 grams of copper sulfate CuSO4 present in the 5.00 grams sample of the compound.
