1. Compound X has a solubility in toluene of 18 mg per 100 mL at 20 °C, and a solubility of 0.64 g per 100 mL at 70 °C. You are given a sample of 0.48 g of compound X which is contaminated with 25 mg of compound Y. A. If compound Y is always soluble in toluene, describe in detail how you could separate Y from X. Would x now be pure? B. If compound Y has approximately the same values of...
How many grams of ethanol, CH3CH2OH, would you dissolve in water to make 2.75 L of vodka (which is an aqueous solution that is 6.86 M ethanol)? Using the density of ethanol (0.789 g/mL), calculate the volumes of ethanol and water you need to make 2.75 L of vodka. Please show all work. Thank you!

Organic chemistry help? 2. Eight grams of compound Y was recrystallized using the minimal amount of boiling water, 103 mL. In a separate experiment, a minimum of 50 mL boiling water was used to dissolve another sample of compound Y. After recrystallization at 20 °C, 95.7% of compound Y was recovered. Calculate the solubility of compound Y in water at 100 oC and 20 oC. (1 pt)
The solubility of compound A ịn water at 25°C is 3.00 g/100 mL. In benzene at the same temperature, the solubility of compound A is 4.00 g/50mL. If 3 g of compound were dissolved in 100 mL of water, how much compound would be extracted by three 10-mL portions of benzene?
The solubility of a compound is 8.4 g per 100 mL in boiling water, 1.9 g per 100 mL in cold water, whereas its solubility in ethanol is 13.8 g per 100 mL at 78 C and 4.2 g per 100 mL at 2 C. Which solvent would be better for the recrystallization of the compound? Explain.
