3.) A solution is reported to be 35.4% ethanol in water. How many grams of ethanol and how many grams of water would there be in 395 grams of solution? S . 39
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!
PART A How many grams of ethanol, CH3CH2OH, should you dissolve in water to make 0.400 L of vodka (which is an aqueous solution that is 6.86 M ethanol)? Express your answer with the appropriate units. PART B Using the density of ethanol (0.789 g/mL), calculate the volume of ethanol you need to make 0.400 L of vodka. Express your answer with the appropriate units.
