Question

12 ml of ethyl alochol and 7ml of water are mixed to pepare a solution which component is solvent ​

Answer 1

Answer:

We take the substance which is present in higher amount as solvent.

In this solution , 1.23 x 10^23 molecules of ethyl alcohol is present. whereas 2.34 x 10^23 molecules of water is present.

Cleary, amount of Water is greater, therefore Water is the solvent.

I calculated molecules of both by the formula:

molecules = 6.02 x 10^23 x density x volume / molar mass
