How many total atoms are there in 74.5 g of carbon dioxide (co2)? i am not sure if i did it correct i ended up getting 1.02 * 10^24 atoms? is that correct

Molar mass CO₂ = 44.0 g/mol

44.0 g 6.02x10²³ molecules
74.5 g ??

74.5 x ( 6.02x10²³) / 44.0

= 1.019x10²⁴ molecules of CO2

Calculate the number of atoms :

CO₂ => 1 atom of Carbon  ,  2 atoms of Oxygen ( 1 + 2 = 3  atoms )

therefore:

1 molecule CO2 3 atoms
1.019x10²⁴ CO2 ?? atoms

3 x ( 1.019x10²⁴) / 1 = 

= 3.057x10²⁴ atoms of CO₂

hope this helps!

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
