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

The Three Mile Island nuclear plant is located in Pennsylvania.
Answer:
Explained Below in explanation.
Explanation:
Looking at the data in the text, we can see that the diameter of the Sun is about 100 times that of Earth, about 1,500,000 km for the Sun compared to about 12,000 km for Earth. A galaxy such as the Milky Way is about 100,000 light-years in diameter. Since a light-year is about 10¹³ km, this means the Galaxy has a diameter of approximately 10¹⁸ km, or about 10¹⁴ times (100 million million times) the radius of Earth. The most distant objects visible define the limits of the visible universe (which is likely only a small part of the entire universe). These objects are about 10 billion light-years away, or 10²³ km. This is 10¹⁹ times (10 billion billion times) the radius of Earth.
