Answer: Option B : B 6.022 × 10 23 C atoms = 12 g 1 C atom = 12 6.022 × 10 23 = 1.99 × 10 − 23 g

The mass of an atom of C is

Question -

The mass of an atom of C is

Options:

A .

1 g

B .

1.99 \times 10^{- 23} g

C .

\frac{1}{12}

D .

1.99 \times 10^{- 20} g

Answer: Option B
:
B

6.022 \times 10^{23}

C atoms = 12 g
1 C atom =

\frac{12}{6.022 \times 10^{23}} = 1.99 \times 10^{- 23} g
