To determine the number of moles of boron in 6.035 x 10^25 atoms of boron, we need to use Avogadro's number, which is 6.022 x 10^23 particles per mole. We can set up a proportion to solve for the number of moles:
(6.035 x 10^25 atoms) / (6.022 x 10^23 atoms/mol) = x moles
Simplifying the expression on the left side, we get:
x = (6.035 / 6.022) x (10^25 / 10^23) moles
x = 1.002 moles
Therefore, there are 1.002 moles of boron in 6.035 x 10^25 atoms of boron.
