Answer:

27 and 24 zeroes following it

Explanation:

10^25 is 100...(continues for 25 zeroes)

Now we multiply it by 2.7, making it 24 zeroes afterwards.

Avogadro's numbers are used to calculate the number of moles from molecules. There are 44.8 moles in MnO.

What are molecules?

Molecules are the unit of the compound that may have the same or different atoms in it. The number of molecules is used to calculate moles from Avogadro's number.

By Avogadros number 1 mole of substance = 6.02 x 10²³ molecules

So, 2.7 x 10²⁵ molecules will have moles:

(2.7 x 10²⁵ molecules × 1 mole) ÷ (6.02 x 10²³ molecules) = 0.448 × 10² moles

Therefore, there are 44.8 moles of MnO.
