How do I determine the number of atoms in 30.0 g of K

WebOne can also find the number of atoms in a sample from the moles of a substance. The bridge between atoms and moles is Avogadro’s number, \(6.022\times 10^{23}\). Avogadro’s number is typically dimensionless, but when it defines the mole, it can be expressed as \(6.022\times 10^{23}\ elementary\ entities\ per mol\). In this form, … WebMar 1, 2016 · One mole of any element contains #6.022xx10^23# atoms of that element. The molar mass of an element is the mass in grams of one mole of the element, which is its relative atomic mass (atomic weight) on the periodic table in g/mol.. Potassium, #"K"#, has the relative atomic mass #39.0983#, therefore its molar mass is #"39.0983 g/mol"#. We … eastern star greetings and responses
