Question

The weight of 1 mole of atoms of an element is called

Answer 1

using information from the periodic table.

A conveniently measured amount of any element that equals the mass in grams of that element is called a mole. One mole of hydrogen weighs 2 grams. One mole of chlorine weighs 70 grams. Just like a dozen equals twelve, a mole equals Avogadro’s number of atoms or 6.02 × 1023. 6.02 × 1023 molecules of hydrogen would weigh 2 grams. An equal number of chlorine molecules would weigh 70 grams. Chlorine is much heavier than hydrogen because it has more protons and neutrons. A similar analogy is that a dozen bowling balls would weigh more than a dozen golf balls. A mole is simply a very large number of atoms. You need a very large number of atoms to be able to measure something you can see, like a teaspoon of salt. The coefficient is given to determine the number of moles in the balanced equation. Using these mole ratios, you can substitute the grams for atomic mass units and calculate relative masses for reactants and products.
