Question

The number of carbon atoms in 22.0 g of CO2, is:​

Answer 1

Answer:

Explanation:

The process is simple for finding the number of carbon atoms in 22 grams of carbon dioxide. At first, we will find the number of moles present in given mass of carbon dioxide and then multiply it by Avogadro constant as well as with the number of moles of carbon present independent in one molecule of carbon dioxide.

MCO2=12+16×2

=44gmol−1

molecular mass of CO2 is 44. Which mean 44 grams of CO2contain Avogadro’s number of atoms. So,

44gmol−1=6.022×1023mol−1(Avogadro’s number)

442=6.022×10232

22g=3.011×1023

So 22g of CO2have  3.011×1023  CO2molecules.

Since one molecule has one carbon atom it also has 3.011×1023 Carbon atoms

Answer 2

there is one carbon atom in each molicule of co2

Explanation:

so the answer is 3.01 x10 to the 23rd carbon atoms in 22g of co2
