Respuesta :
Mass in kilogram = ?
Avogadro’s number = 6.022 x 10^23
Average mass of a person = 160 lb
First we convert mass into kilogram,
1 lb = 0.4536 kg
160 lb = 72.576 kg
Now multiply the Avogadro’s number people with the average mass in kilogram
6.022 x 10^23 x 72.576 = 4.37 x 10²⁵ kg
4.37 x 10²⁵ kg is the mass in kilogram of Avogadro's number of people.
Answer: Mass of an Avogadro's number of people is [tex]4.3695632 \times 10^{25} kg[/tex].
Explanation:
Average mass of the person = 160 lb
Avogadro number = [tex]N_A=6.022\times 10^{23}[/tex]
Mass of an Avogadro's number of people = [tex]6.022\times 10^{23}\times 160 lb=9.6352\times 10^{25} lb[/tex]
1 lb = 0.4535 kg
[tex]9.6352\times 10^{25} lb=9.6352\times 10^{25}\times 0.4535 kg=4.3695632 \times 10^{25} kg[/tex]
Mass of an Avogadro's number of people is [tex]4.3695632 \times 10^{25} kg[/tex].
