Answer:

True

Explanation:

Water vapor is totally invisible.

Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.

How many atoms are there in 24 moles of Fe?

Semenov [28]

Answer: There are $145 \times 10^{23}$ atoms in 24 moles of Fe.

Explanation:

According to the mole concept, 1 mole of a substance contains $6.022 \times 10^{23}$ atoms.

Therefore, atoms present in 24 moles of Fe are calculated as follows.

$24 mol \times 6.022 \times 10^{23} atoms/mol\\= 144.52 \times 10^{23} atoms\\or, 145 \times 10^{23} atoms$

Thus, we can conclude that there are $145 \times 10^{23}$ atoms in 24 moles of Fe.
