Question 1 Report
On evaporation to dryness, 3503 of saturated solution of salt Z gave 55.5g of salt. What is the solubility of the salt? [Z = 101]
The solubility of a salt is defined as the maximum amount of solute that can be dissolved in a given amount of solvent at a specified temperature and pressure. Given that 3503 of saturated solution of salt Z gave 55.5g of salt. We can find the solubility of the salt using the formula: Solubility = Mass of solute / Volume of solution First, we need to convert the given mass of salt to moles using its molar mass: Molar mass of Z = 101g/mol Number of moles of Z = 55.5g / 101g/mol = 0.5495 mol Now, we can calculate the volume of the solution using the given volume of 3503: Volume of solution = 3503 = 0.35 dm3 Substituting the values into the formula, we get: Solubility = 0.5495 mol / 0.35 dm3 = 1.57 moldm-3 Therefore, the solubility of salt Z is 1.57 moldm-3.
