Question

What is the mass of 2.044 x 10^23 carbon atom? *

Answer 1

The mass of 2.044 * 10/23 carbon atoms

since 6.022*10 raised to power 23 atoms of carbon weighs 12gm........ so 12.044*10 raised to power 23 atoms of carbon weighs 24gm

Answer 2

Given:

$2.044×10^{23}$ number of carbon atoms.

To find:

The mass.

Solution:

Carbon is group 14 elements. It has an atomic number of 6. The atomic mass of a C atom is 12 grams.

Thus we can write-

12 grams of carbon atom has $6.022×10^{23}$ number of carbon atoms.

$6.022×10^{23}$ number of carbon atoms has a mass of 12 grams.

Hence $2.044×10^{23}$ number of carbon atoms has a mass of $2.044×10^{23}×12/6.022×10^{23}\\=4.07$.

Hence $2.044×10^{23}$ number of carbon atoms has a mass of 4.07 grams.
