Document Summary
People mess up converting between moles and grams because of two things, one of which was not understanding what a mole really is. The other thing is that different elements have different masses; that is, different numbers of elements have different gram values for one mole. This is where atomic mass comes in handy. How many moles are there in 8. 006 grams of helium. Below is an element from the periodic table. We"re not interested in the elemental symbol after we determine which element we are trying to convert for. The atomic mass becomes our conversion factor; that means, there are. What we need to do now is set up a conversion chart. Atoms are not indivisible blocks of matter; they are composed of even smaller particles. We once thought this, but after many revisions to the atomic model, we figured out the atom is composed of 2 parts and 3 particles.
