Calculate the no. of particles in each of the following:7g of nitrogen

1.	Calculate the no. of particles in each of the following:7g of nitrogen molecules.5 moles of carbon atoms {given that N=14u; C=12u, N0=6.022*1023 mol -1}
Answer» MASS of nitrogen= 14 g Given mass= 7 g Moles= Given mass/ MOLECULAR mass =7/14= 1/2 mole =1/2× 6.022×10^23 = 3.011×10^23 (Actually, AVOGADRO CONSTANT= 6.023×10^23)

Calculate the no. of particles in each of the following:7g of nitrogen molecules.5 moles of carbon atoms {given that N=14u; C=12u, N0=6.022*1023 mol -1}

Answer»

MASS of nitrogen= 14 g

Given mass= 7 g

Moles= Given mass/ MOLECULAR mass

=7/14= 1/2 mole

=1/2× 6.022×10^23

= 3.011×10^23

(Actually, AVOGADRO CONSTANT= 6.023×10^23)
