Respuesta :
Mole: the amount of a substance that contains 6.02 x 10. 23 respective particles of that substance. Avogadro's number: 6.02 x 10. 23. Molar Mass: the mass of one mole of an element. CONVERSION FACTORS: 1 mole = 6.02 x 10. 23 atoms 1 mole = atomic mass (g). Try: 1. How many atoms are in 6.5moles of zinc
Answer:
53.97 moles
Explanation:
First off, it is important to understand the following concepts;
Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale.
Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to [tex]6.022 * 10^{23}[/tex] mol-1 and is expressed as the symbol NA.
Hence, the relationship between number of moles and number of atoms is given as;
1 mole = [tex]6.022 * 10^{23}[/tex] atoms
The question asks to find the number of moles [tex]3.25 * 10^{25}[/tex] atoms equals to.
so we have;
1 = [tex]6.022 * 10^{23}[/tex]
x = [tex]3.25 * 10^{25}[/tex]
upon cross multiplication, we are left with;
x = (1 * [tex]3.25 * 10^{25}[/tex] ) / [tex]6.022 * 10^{23}[/tex]
x = 53.97 moles
