# Given 2*g masses EACH of silicon, tin, sulfur, and selenium, which sample contains the MOST atoms?

Apr 23, 2017

Well, what are the molar masses of each element?

#### Explanation:

$\text{Silicon,}$ $28.1 \cdot g \cdot m o {l}^{-} 1$.

$\text{Selenium,}$ $79.0 \cdot g \cdot m o {l}^{-} 1$.

$\text{Tin,}$ $118.7 \cdot g \cdot m o {l}^{-} 1$.

$\text{Sulfur,}$ $32.1 \cdot g \cdot m o {l}^{-} 1$.

And clearly, because silicon has the LOWEST atomic mass, a $2.00 \cdot g$ mass of silicon, has the GREATEST number of atoms. How many atoms does this mass of silicon contain?
