Question

Find the number of atoms and mole present in 0.2 mole of urea​

Answer 1

Explanation:

no.of mole =0.2

number of atom is= 0.2×6.022×10^23 =1.204 ×10^23

Answer 2

number of molecules present in 0.2 mol urea =

$1.204 \times {10}^{23}$

number of atoms present in 0.2 mol urea =

$8 \times 0.2 \times 6.022 \times {10}^{23} \\ \\ = 2.4 \times {10}^{24}$
