Question
20mL ethanol(density=o.789g/mol) is dissolved in sufficient water to produce a 200mL solution. the density of the solution is 0.982g/mL. what is the molarity?
Answers
Use density of ethanol to convert mL ethanol to grams. Then mol = grams/molar mass.
Then M = mols/L solution.
Then M = mols/L solution.
