Determine the mass

Question

Determine the mass in grams of 5.52 * 10²¹ atoms of carbon. the mass of one mole of carbon is 12.01g

Answer 1

There are 6.022 x 10²³ atoms in a mole. That means you have (5.52 x 10²¹)/6.022 x 10²³) or 0.009166 moles of carbon. To determine the mass, multiply 12.01 grams/mole by 0.009166 moles to get 0.110 grams
