Question

If one mole of carbon weighs 12 grams, what is the mass (in grams) of 1 atom of carbon?

• A. $\frac{12}{6.023\times {10}^{23}}$
• B. $\frac{6}{6.023\times {10}^{23}}$
• C. $\frac{1}{6.023\times {10}^{23}}$
• D. $\frac{3}{6.023\times {10}^{23}}$

Answer 1

Answer: (A)

$\frac{12}{6.023\times {10}^{23}}$

One mole = $6.023\times {10}^{23}atoms=12g$
Mass of 1 atom = $\frac{12}{6.023\times {10}^{23}}$
