Question

calculate the mass of 3.011 *10^24 atoms of carbon

Answer 1

I hope you got your answer....

Answer 2

The mass of $3.011\times 10^{24}$ atoms of carbon is 60 grams.

Explanation:

Number of carbon atoms = $3.011\times 10^{24}$

Molar mass of carbon = 12 g/mole

Firstly, we have to calculate the moles of carbon atom.

In 1 mole of carbon, number of carbon atoms are $6.022\times 10^{23}$

So, $3.011\times 10^{24}$ of carbon present in $\dfrac{3.011\times 10^{24}}{6.022\times 10^{23}}=5$ moles of carbon.

So, the mass of carbon atom is :

$\text{Mass of C}=\text{Moles of C}\times \text{Molar mass of C}\\\text{Mass of C}=(5moles)\times (12g/mole)=60g$

So, the mass of $3.011\times 10^{24}$ atoms of carbon is 60 grams. Hence, this is the required solution.
