If the mass of an apple is 100g on average and the mass of the earth is approximately 6.0 * 10^24kg how many apples would it take to equal the mass of the earth?
The average atomic mass of neon is thus: The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.
