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.

i believe the answer is 5,000
