Question

2. Calculate maximum amount of sodium chloride that can be dissolved in 2.0 g of water at2 C? (Refer to Figure 5 in the Background section.) 3. Seltzer is a beverage made by dissolving carbon dioxide in water. Carbon dioxide (CO2) solubiliy s about 1.7 grams per kilogram in water at room temperature. What compound is the solute? What compound is the solvent? . Solute->sehzer 'Solvent bubbles 4. Is sugar more soluble in hot tea or cold tea? What does this tell us about the solubility of sugar as a function of temperature? Sugar :11 more soluble in hot tea because there will be more colisons since the increased tcmperature increase the kinethic energy

Explanation / Answer

Given

mass of water = 2 g

at 25 C water density will be 1 g/ml

hence volume of water = 2 ml

solubility of NaCl in water = 0.359 g/ml

Amount of NaCl that can be dissolved = 0.359 g/ml * 2ml = 0.718 g

Answer 0.718 g of NaCl
