Give brief answers to the following question:
A sample of vitamic C is known to contain \(2.58\) × \(10^2{^4}\) oxygen atoms.
How many moles of oxygen atoms are present in the sample?
How many moles of oxygen atoms are present in the sample?
1 mole of oxygen atoms = × \(10^2{^3}\) atoms.
∴ Number of moles of oxygen atoms = × \(10^2{^4}\) / \(6.023\) × \(10^2{^3}\).
= mol.
= 4.28 moles of oxygen atoms.
