Question

The number of atoms present in 4.8g of carbon -12 is

Answer 1

$\textbf{\huge{\underline{ Hello Mate! }}}$

Though atoms and molecules are two distinct things but yet we treat its as equal while solving numericals.

Weight of carbon given = 4.8 g

Atomic mass of carbon = 12 g/mol

No. of atoms ( molecules ) = (Weight in g / weight in g per mol) × Avargrado no.

$= \frac{4.8 \: g}{12 \: g {m}^{ - 1} } \times 6.022 \times {10}^{23} \\ \\ = 0.4 \times 6.022 \times {10}^{23} \\ \\ = 2.41 \times {10}^{23}$
