Question

30 cm cubic of water was mixed with 30 cm cubic of ethanol. the final. volume of the misturr was found to be less than 60cm cubic .Give the reason why

​

Answer 1

Answer: in mixture water molecules comes closer to ethanol molecules because of hydrogen Bonds. Then smaller water molecules occupy less volume than in pure water.

Explanation: water molecules are smaller than ethanol molecules.

Both form Hydrogen bonds in pure form and in water-ethanol mixture.

Water molecules fill better space between ethanol molecules.

I think volume of the mixturecoild be 59.6 -59.8 cubic cm
