Question

Find the number of atoms in0.5 mole of c atom

Answer 1

$<b>No. of atoms / molecules / ions = No. of moles × Avogadro's constant</b>$

No. of moles = $\tt{0.5}$

Avogadro's constant = $\tt{6.022 × {10}^{23}}$

No. of atoms = $\tt{0.5 × 6.022 × {10}^{23}}$

No. of atoms = $\tt{3.011 × {10}^{23}}$

Answer 2

Step by step explanation:

Given : Carbon atom has $0.5$  moles.

To find : The number of atoms.

Formula used : For finding the number of atoms,

Number of atoms of any compound  $=$ no. of moles of that compound × Avogadro number ($N_A$)

• Calculation for number of atoms

We have no. of moles of carbon atom is  $0.5$  moles.

By using formula,

Number of atoms of C $=$ no. of moles of C × Avogadro number ($N_A$)

As we know Avogadro number,

$N_A=6.023*10^{23}$

Number of atoms of C $=0.5*6.023*10^{23}$

                                      $=3.012*10^{23}$ atoms.

Hence we get the number of atoms of C are $3.012*10^{23}$ atoms.
