Question

(b) what number, in addition to the answer to part (a), is needed to determine the number of atoms of ca in the sample? note: cabr₂, 1 mol cabr₂ = 2 mol br, 1 mol cabr₂ = 1 mol ca. challenge problems

Explanation:

Step1: Recall atom - mole relation

To find number of atoms from moles, we use Avogadro's number.

Answer:

Avogadro's number ($6.022\times 10^{23}$ atoms/mol)
