In the world of chemisty, a 'mole is a number of something a very lary large number of something. just as a dozen is 12 of something, a mole is about 6.02 * 10^23 of something . in chemistry, we like to measure the number of atoms or molecules in moles. if one mole is equal to 6.02 * 10^23 atoms, and you have 8.00 * 10 ^23 atoms, then how many moles do you have ?

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?
