what is the approximate size of a molecule... pls tell
Answers
Answer:
Matter is made up of molecules which are very small in size (~10-9 m).
Explanation:
Hey, you can calculate it yourself, for any pure substance. For example, 18 g of water takes up 18 ml of space. It also consists of 6.023 x 10E23 molecules of water so just divided the number of molecules into the 18 ml and you will have the amount of space that each water molecule takes up.
You can do this calculation for any other pure substance. Just look up the molar mass of the substance. If you take that mass of the substance and divide it by the density of the substance (also easy to look up) you will have calculated the molar volume of the substance, just like the 18 ml value for water. That value is the space that 6.023 x 10E23 molecules of the substance take up and again simple division gives you the amount of space one molecule takes up.
Amaze your friends and loved ones. Do the calculation in front of them. Learn to do it in your head and amaze everyone!
