Answer:

The atom of carbon weighs more

Explanation:

we have

Atom of carbon weighs

$1.99*10^(-22)\ g=1.99*10^(-22)((10^(5))/(10^(5)))=199,000*10^(-22)((1)/(10^(5)))=199,000*10^(-27)\ g$

Atom of hydrogen weighs

$1.67*10^(-27)\ g$

Compare

$199,000*10^(-27)\ g > 1.67*10^(-27)\ g$

therefore

The atom of carbon weighs more
