The mass in grams of given atoms of carbon is 0.1545g.

Given that,

  • The number of carbon atoms is 7.75 × 10^21.
  • The mass of one mole of carbon is 12.01g.

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.
