Just as a 'dozen' 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 7.00 * 10^23 atoms, then how many moles do you have?

How many moles are in 43.9 l of oxygen

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.

What is the molarity of the solution produced when 145 g of nacl is dissolved in sufficient water to prepare 2.75 l of solution?
