Answer:
5*10^25 atoms of carbon
Explanation:
Check from the periodic table:
M(carbon) = 12.01 g/mol
Convert kg into g:
1 kg = 1000 g
Calculate the number of moles of carbon:
n(carbon) = (1000 g) ÷ (12.01 g/mol) = 83.26 mol
Convert moles into number of particles:
#(carbon) = n × NA = 83.26 mol × 6*10^23
= 5*10^25 particles
Note: NA represents the Avogadro's Number, which has the value 6.02*10^23 particles/mol.
