Explanation:

Step1: Recall the conversion steps

To convert atoms of a substance to grams, we first use Avogadro's number ($6.022\times 10^{23}$ atoms/mol) to convert atoms to moles, and then use the molar - mass of the substance to convert moles to grams.

Step2: Convert atoms to moles

The number we multiply the number of atoms of rubidium by to get moles is $\frac{1}{6.022\times 10^{23}\text{ atoms/mol}}$. The unit of the number of atoms cancels out, and we get moles.

Step3: Convert moles to grams

The molar mass of rubidium (Rb) is approximately $85.47$ g/mol. We multiply the number of moles of Rb by $85.47$ g/mol to get grams of Rb.

Answer:

First number: $\frac{1}{6.022\times 10^{23}}$, First unit: mol/atom; Second number: $85.47$, Second unit: g/mol
