If one atom of carbon weighs 1.99 × 10^−22 g and one atom of hydrogen weighs 1.67 × 10^−27 g, which element weighs more? Explain

garik1379 [7]

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
