Question

How many miles are in 8.73 *10^25 atoms of boron

Answer 1

The correct question is: How many moles are in $8.73 \times 10^{25}$ atoms of boron.

Answer: There are 145 moles present in $8.73 \times 10^{25}$ atoms of boron.

Explanation:

According to the mole concept, there are $6.022 \times 10^{23}$ atoms present in one mole of every substance.

Hence, number of moles present in $8.73 \times 10^{25}$ atoms is calculated as follows.

$Moles = \frac{8.73 \times 10^{25}}{6.022 \times 10^{23}}\\= 1.45 \times 10^{2}\\= 145 mol$

Thus, we can conclude that there are 145 moles present in $8.73 \times 10^{25}$ atoms of boron.
