Question

Mass of one atom of oxygen is:

• A. $\frac{16}{6.023\times {10}^{23}}g$
• B. $\frac{32}{6.023\times {10}^{23}}g$
• C. $\frac{1}{6.023\times {10}^{23}}g$
• D. $8u$

Answer 1

Answer: (A)

$\frac{16}{6.023\times {10}^{23}}g$

Mass of $6.023\times {10}^{23}$ atoms of oxygen = Atomic mass of oxygen = 16 g

Mass of one atom of oxygen =$\frac{16}{6.023\times {10}^{23}}$g
