Web1. The number of atoms in 30.0g of K would be 4.632 * 1023 atoms. By using the Avogadro's number, the 1 mole of a substance contains 6.022*1023 atoms. Mole of 30.0g of K = 30/39 = 0.7692 moles Hence, 0.7692 moles of K would contain = 0.7692*6.022*102 …. View the full answer. Transcribed image text: WebThe procedure to use the grams to atoms calculator is as follows: Step 1: Enter the atomic mass number, grams and x in the respective input field.

One mole of anything, including atoms, is 6.022xx10^23 (Avogadro's number) of them. Usually you will have a given mass of an element. There are two basic steps to get from the given mass to the number of atoms. They are: "Mass"rarr"Moles" and "Moles"rarr"Atoms" The following example will show … WebNov 8, 2015 · So, neon has a molar mass of 20.18 g/mol, which means that every mole of neon has a mass of 20.18 g. Your sample of neon will thus contain. 5.9g ⋅ 1 mole Ne 20.18g = 0.2924 moles Ne. Now, you know that one mole of any element contains exactly 6.022 ⋅ 1023 atoms of that element - this is Avogadro's number. Well, if one mole … simple rainbow cake design
