Question

Convert 6.71 moles NH3 to number of molecules.

Answer 1

Answer: There are
`40.41 * 10^(23)` molecules present in 6.71 moles of
`NH_(3)`.

Step-by-step explanation:

Given: Moles of
`NH_(3)` = 6.71 mol

According to the mole concept, 1 mole of every substance contains
`6.022 * 10^(22)` molecules.

Therefore, molecules present in 6.71 moles are calculated as follows.

`Molecules = moles * 6.022 * 10^(23)\\= 6.71 * 6.022 * 10^(23)\\= 40.41 * 10^(23)`

Thus, we can conclude that there are
`40.41 * 10^(23)` molecules present in 6.71 moles of
`NH_(3)`.
