Answer:
[tex]1.7\times 10^{-12}[/tex] moles of carbon
Explanation:
1 trillion = [tex]10^{12}[/tex]
Avogadro number :It is the number of particles that are present in 1 mole of substance.
[tex]N_{0} = 6.022\times 10^{23}[/tex]
So,
[tex]6.022\times 10^{23}[/tex] atoms = 1 mole carbon
1 atom =
[tex]\frac{1}{6.022\times 10^{23}}[/tex] mole
1 trillion atom =
[tex]\frac{1}{6.022\times 10^{23}}\times 10^{12}[/tex] mole
[tex]1.660\times 10^{-12}[/tex] mol
Two significant figure
[tex]1.7\times 10^{-12}[/tex] moles of carbon
