How many atoms are in a sample of carbon weighing 16 grams? Round your answer to two decimal places.
Group of answer choices

9.63 x 10^24 atoms

1.33 atoms

2.20 x 10^22 atoms

8.01 x 10^23 atoms

d) 8.01 E23 atoms

Explanation:

∴ mass C = 16 g

∴ molar mass C = 12.0107 g/mol

⇒ mol C = (16 g)*(mol/12.0107 g) = 1.332 mol

⇒ atoms C = (1.332 mol)*(6.022 E23 atoms/mol)

⇒ atoms C = 8.02 E23 atoms

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
