To calculate the mass of a given number of atoms of an element, you need to know the molar mass of that element. The molar mass of an element is the mass of one mole of atoms of that element.
The molar mass of fluorine (F) is approximately 19 grams per mole (g/mol).
Given that you have 9.7x10^24 atoms of fluorine, we can calculate the mass using the following steps:
Convert the given number of atoms to moles by dividing by Avogadro's number, which is approximately 6.022x10^23 atoms/mol:
Moles of fluorine = (9.7x10^24 atoms) / (6.022x10^23 atoms/mol)
Multiply the moles of fluorine by the molar mass of fluorine:
Mass of fluorine = Moles of fluorine × Molar mass of fluorine
Mass of fluorine = (9.7x10^24 atoms / 6.022x10^23 atoms/mol) × (19 g/mol)
Performing the calculation gives us:
Mass of fluorine = 32.13 grams
Therefore, the mass of 9.7x10^24 atoms of fluorine is approximately 32.13 grams.
