Question

A sample of vitamin C is known to contain 2.58 x ${10}^{24}$oxygen atoms. How many moles of oxygen atoms are present in the sample?

Answer 1

We know that

1 mole of oxygen atom=$6.022\times {10}^{24}atoms$

Number of moles of Oxygen atoms=$\frac{2.58\times {10}^{24}}{6.022\times {10}^{23}}=4.28mol$

So, 4.28 oxygen atoms are present in the given sample of vitamin C
