Answer:

The atom of carbon weighs more

Step-by-step explanation:

we have

<em>Atom of carbon weighs</em>

1.99*10^{-22}\ g=1.99*10^{-22}(\frac{10^{5}}{10^{5}})=199,000*10^{-22}(\frac{1}{10^{5}})=199,000*10^{-27}\ g

<em>Atom of hydrogen weighs</em>

1.67*10^{-27}\ g

Compare

199,000*10^{-27}\ g > 1.67*10^{-27}\ g

therefore

The atom of carbon weighs more
