CORRECT! Good job!

You have used the right piece of data. Good. Now, make sure you multiplied by Avogadro number to determine what is the volume of Avogadro number of drops. (Pay attention: Avogadro number is 6.022*1023).

You have used the right piece of data. Good. Now, make sure you have made right the units swiching. Maybe you forget to raise to a power of 3 the volume of the Kinneret? (Pay attention: it was given that it is km3 in the data given upward on the image).

You have made the units switching correctly. Good. Now, make sure you have chosen the right item of data given upward on the image. (Pay attention: you should use only one piece of the data given correctly).
