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 <span>of atoms :
CO</span>₂<span> => 1 atom of Carbon , 2 atoms of Oxygen ( 1 + 2 = 3 atoms )
therefore:
</span>
1 molecule CO2 ---------------------- 3 atoms
1.019x10²⁴ CO2 --------------------- ?? atoms
3 x ( 1.019x10²⁴) / 1 =
= 3.057x10²⁴ atoms of CO₂
hope this helps!
The value 2600 will satisfactorily convert 1.56km to 60cm
Explanation:
To change a number from one to another, we need a conversion factor like that number fulfills the equality requirement to make them the same.
The aim here is to find the number.
We are working with the unit of distance here.
Let us make our conversion factor = K
1.56km x K = 60cm
So that K = 
Now let us convert 60cm to km;
1000m = 1km
100cm = 1m
60cm x
x 
= 0.0006km
now;
K =
= 2600
The value 2600 will satisfactorily convert 1.56km to 60cm
