How many moles of oxygen atoms are in 2.50 mol of kmno4

Answer : The number of moles of oxygen atoms are 10 moles.

Explanation : Given,

Moles of = 2.50 moles

By the stoichiometry we can say that in , there are 1 moles of potassium atom, 1 mole of manganese atom and 4 moles of oxygen atoms.

That means,

As, 1 mole of contains 4 moles of oxygen atoms

So, 2.50 mole of contains moles of oxygen atoms

Therefore, the number of moles of oxygen atoms are 10 moles.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
