Format for the answer is ___ x 10 exponent

_ x 10 _

Give value to four significant figures.

Answer 1

Answer:

very specific...sus...yea no one knows

Step-by-step explanation:

In order to determine the mass of one atom of an element, you must determine its molar mass, which is its atomic weight on the periodic table in g/mol, and you need to know the relationship between moles and the number of atoms: 1 mol of atoms = 6.022×1023 atoms . Then divide the molar mass by 6.022×1023 atoms/mol .
