Question

how many atoms are present in 0.44 grams of carbon dioxide​

Answer 1

Molecular weight of CO2 = 44
1 mol of CO2 weighs 44 g
0.44g of CO2 = 0.44/44 = 0.01 mol.
1 mol of CO2 contains Avogadros number of molecules
= 6.022*10^23 molecules
0.01 mol of CO2 contains 0.01*6.022*10^23 molecules = 6.022*10^21 molecule.
Each molecule of CO2 contains 1 C atom.
So there are 6.022*10^21 carbon atoms in 0.44g of CO2...

Answer 2

Answer:

6.022 x 10^22

Explanation

44g =1 mole of co2

4.4g = ? mole   of co2

?= .1 mole

therefore

no of atoms of co2= .1 x 6.022 x 10^23

                                  =6.022 x 10^22
