Calculate the solubility of CuSO4 5H2O at 0 C in grams of solute per 100 g water.
To calculate the solubility of CuSO4·5H2O (copper(II) sulfate pentahydrate) at 0°C in grams of solute per 100 g water, we can utilize the solubility data.
1. Begin by researching the solubility of CuSO4·5H2O at 0°C. You can refer to credible sources such as scientific literature, chemistry textbooks, or reputable online databases like the CRC Handbook of Chemistry and Physics.
2. Once you have the solubility value, it is typically expressed in terms of grams of solute per 100 mL (or grams per deciliter) of water. However, we need to convert it to grams of solute per 100 g of water.
3. To convert from grams per deciliter to grams per 100 g, you need to determine the density of water at 0°C. At this temperature, the density of water is approximately 0.998 g/mL or 0.998 g/cm³.
4. Calculate the mass of water corresponding to 100 g using the density of water. In this case, it would be 100 g / 0.998 g/mL = 100.2 mL or 100.2 g.
5. Finally, apply the conversion factor to calculate the solubility of CuSO4·5H2O in grams of solute per 100 g water.
Remember, the exact solubility value depends on the specific conditions and purity of the compound, so ensure you obtain the most accurate value from reliable sources.
