find the no of gram atoms of the following element:
0.95 g of carbon
Asked by B Shreya Goud | 09 Oct, 2015, 04:46: PM
answered-by-expert Expert Answer
One mole of carbon atom is equivalent to 12 g of carbon.
 
Therefore, 0.95 g of carbon is = 0.95/12 moles = 0.08 moles.
 
Now, one mole contains 6.02 × 1023 atoms, i.e. equal to Avogadro's number.
 
So, 0.08 moles contains
 
n = 0.08 × 6.02 × 1023 = 4.8 × 1022 atoms
