Question

A sample of vitamin C is known to contain 2.58 * 1024 oxygen atoms. How many moles of oxygen atoms are present in the sample.

Plzzzzzzz It's Urgent yaar

Answer 1

6.023*10^23 oxygen atoms = 1 mole of oxygen atoms
1 oxygen atoms =1/6.023 *10^23 mole of oxygen atoms
2.58 * 1024 oxygen atoms =2.58*10^24/6.023*10^23 mole of oxygen atoms
=0.428*10
=4.28

Answer 2

Answer:

Explanation:

6.023*10^23 oxygen atoms = 1 mole of oxygen atoms

1 oxygen atoms =1/6.023 *10^23 mole of oxygen atoms

2.58 * 1024 oxygen atoms =2.58*10^24/6.023*10^23 mole of oxygen atoms

=0.428*10

=4.28
