Question

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

Answer 1

There are 10.00 moles of oxygen atoms in 2.50 mol of KMnO4.

Step-by-step explanation:

To calculate the number of moles of oxygen atoms in 2.50 mol of potassium permanganate (KMnO4), we need to consider the formula of KMnO4. Each molecule of KMnO4 contains four oxygen atoms. Therefore, the number of moles of oxygen atoms is 4 times the number of moles of KMnO4.

Using this information:

• Number of moles of KMnO4 = 2.50 mol
• Number of moles of oxygen atoms = 4 × 2.50 mol = 10.00 mol

Therefore, there are 10.00 moles of oxygen atoms in 2.50 mol of KMnO4.

Answer 2

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

Explanation : Given,

Moles of
`KMnO_4` = 2.50 moles

By the stoichiometry we can say that in
`KMnO_4`, there are 1 moles of potassium atom, 1 mole of manganese atom and 4 moles of oxygen atoms.

That means,

As, 1 mole of
`KMnO_4` contains 4 moles of oxygen atoms

So, 2.50 mole of
`KMnO_4` contains
`2.50* 4=10` moles of oxygen atoms

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