Question 1 one mole of carbon is how many grams? = gramsblank 1: 12question 2 select the best reason as to why chemists use moles in chemistry: aatoms are easily observable and measured on the atomic level batoms are too small to measure and observe so we use lots of atoms instead catoms essentially behave like the mammal moles dchemists do not chemistry students to understand chemistryquestion 3how many moles of skittles are in 2.11 x 1024 skittles? you may use dimensional analysis to convert from skittles to moles. 1 mole = 6.02x1023 particles.= mols of skittlesblank 1: question 4 how many atoms, particles, molecules, or formula units are in one mole of a substance? = (three sig figs)-use the following format example to enter in your 1x10^4 blank 1:
