To convert the mass of CuSO4 * 5H2O to moles, you can use the formula: moles=mass (g)molar mass (g\/mol)\\text{moles} = \\frac{\\text{mass (g)}}{\\text{molar mass (g\/mol)}}moles=molar mass (g\/mol)mass (g)\u200b<\/p>\n\n\n\n
Step 1: Identify the molar mass of CuSO4 * 5H2O.<\/h3>\n\n\n\n
The molar mass of CuSO4 * 5H2O is provided as 249.7 g\/mol. This is the total mass of one mole of copper(II) sulfate pentahydrate.<\/p>\n\n\n\n
Step 2: Find the mass of CuSO4 * 5H2O.<\/h3>\n\n\n\n
Let’s say you have a specific mass of CuSO4 * 5H2O. For example, if you have 10.0 g of CuSO4 * 5H2O, you can substitute this value into the formula: moles of CuSO4 * 5H2O=10.0 g249.7 g\/mol\\text{moles of CuSO4 * 5H2O} = \\frac{\\text{10.0 g}}{\\text{249.7 g\/mol}} moles of CuSO4 * 5H2O=249.7 g\/mol10.0 g\u200b<\/p>\n\n\n\n
Step 3: Calculate the moles.<\/h3>\n\n\n\n
Performing the division: moles=10.0249.7\u22480.0400 moles\\text{moles} = \\frac{10.0}{249.7} \\approx 0.0400 \\text{ moles}moles=249.710.0\u200b\u22480.0400 moles<\/p>\n\n\n\n
Step 4: Conclusion<\/h3>\n\n\n\n
So, for a 10.0 g sample of CuSO4 * 5H2O, the number of moles would be approximately 0.0400 moles. This conversion is important in stoichiometric calculations because it allows you to relate the mass of a substance to the number of particles (atoms, molecules, or ions) it contains.<\/p>\n\n\n\n
Always remember that the molar mass accounts for the masses of all elements present in the compound, including the water molecules in the hydrate. For CuSO4 * 5H2O, the molar mass includes copper, sulfur, oxygen, and the five water molecules.<\/p>\n\n\n\n Convert mass of CuSO4 to moles. Use the molar mass of CuSO4 * 5H2O (249.7 g\/mol). The Correct Answer and Explanation is: To convert the mass of CuSO4 * 5H2O to moles, you can use the formula: moles=mass (g)molar mass (g\/mol)\\text{moles} = \\frac{\\text{mass (g)}}{\\text{molar mass (g\/mol)}}moles=molar mass (g\/mol)mass (g)\u200b Step 1: Identify the molar mass of CuSO4 * 5H2O.
