5.25 x 10^32 atoms of K to grams
NNADVOKAT [17]

Answer:

3.40x10¹⁰ grams

Explanation:

First we<u> convert 5.25x10³² atoms to moles</u>, using <em>Avogadro's number</em>:

5.25x10³² atoms ÷ 6.023x10²³ atoms/mol = 88.72x10⁸ mol

Then we<u> convert K moles to grams</u>, using its <em>molar mass</em>:

88.72x10⁸ mol * 39 g/mol = 3.40x10¹⁰ g

So 5.25x10³² atoms of K would weigh 3.40x10¹⁰ grams.
