Question

3.11 x 10^24 atoms I to grams

Answer 1

`656.10\text{ g}`

Step-by-step explanation:

Here, we want to convert the given number of atoms to grams

We start by getting the number of moles

Mathematically:

`1\text{ mole = 6.02 }*\text{ 10}^(23)\text{ atoms}`

Now, let us get the number of moles in the given number of atoms

We have that as:

`\begin{gathered} \frac{3.11\text{ }*\text{ 10}^(24)\text{ atoms}}{1}\text{ }*\frac{1\text{ mole}}{6.02\text{ }*\text{ 10}^(23)\text{ atoms}} \\ \\ =\text{ }5.2\text{ moles} \end{gathered}`

Now, to get the mass, we have to multiply the above number of moles by the atomic mass of iodine

The atomic mass of iodine is 127 atomic mass units

Thus, we have the mass as:

`\text{ 5.2 }*\text{ 127 = 656.10 g}`
