The mass in grams of given atoms of carbon is 0.1545g.
Given that,
As we know that
One mole of elements is 6.023 × 10^23 atoms.
So, for 7.75 × 20^21 carbon atoms, the mass in grams is
= (12.01 × 7.75 × 20^21) ÷ (6.023 × 10^23)
= 0.1545g of carbon
Therefore we can conclude that the mass in grams of given atoms of carbon is 0.1545g.
