Question

number of atoms that make up each the compound.

2KMnO4

Answer 1

Answer:

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.

Explanation:

try by these method

Answer 2

Answer:

There are generally 2 Potassium(K) atoms,2Manganese(Mn)atoms , 8 Oxygen(O) atoms in $2KMnO_4$

How many atoms are in a compound?

Avogadro's number is a very important relationship to remember: 1 mole = 6.022×10^23  atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
