Question

How many grams of magnesium are in sample containing 9.12+ 10 ^23atoms

Answer 1

Answer: There are 1.51 moles present in
`9.12 * 10^(23)` atoms.

Step-by-step explanation:

According to the mole concept, there are
`6.022 * 10^(23)` atoms present in one mole of every substance.

Hence, moles present in
`9.12 * 10^(23)` atoms are calculated as follows.

`Moles = (9.12 * 10^(23))/(6.022 * 10^(23))\\= 1.51 mol`

Thus, we can conclude that there are 1.51 moles present in
`9.12 * 10^(23)` atoms.
