What is the molarity of a 7.48 m solution of ethanol (C2H5OH) if the density of this solution is 0.869 g/ml?

Solutions

Expert Solution

Molarity = 4.83 M

While solving for molarity we have taken the volume of the final solution instead of taking is 1000 ml because we are asked for the molarity of the same solution.

I've explained this solution as much as I could have as it is a numerical based question. Please give a positive rating if you liked the answer. Thank you : )

Note :- we don't need to fill the table completely as the following data is enough to calculate the molarity of the same solution.
