Question

how many atoms are there exactly 12 grams of carbon 12 elements

Answer 1

6.022*10^23 atoms are present in carbon 12 element

Answer 2

$6.023\times 10^{23}$ atoms of C-12 $(C)$ are there exactly 12 grams of carbon 12 elements.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{12g}{12g/mol}=1mole$

1 mole of C-12 $(C)$ contains= $6.023\times 10^{23}$ atoms of C-12 $(C)$
