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.
