Question

calculate the number of moles in 3.011*10 ki power 23 atom of c​

Answer 1

We know that,

1 mole = 6.022×10²³

6.022×10²³ is known as the Avogadro number.

Given number of particles = 3·011×10²³  

The number of moles in 3·011×10²³ atom of carbon = $\frac{given number of particles}{Avogadro number}$

                                    = $\frac{3·011×10²³}{6·022×10²³}$

                                    = 0·5

Therefore, number of moles in 3·011×10²³ atom of carbon is 0·5
