Respuesta :
The moles of carbon that are in the sample of 21.45 moles of heptane(C₇H₁₆) is 150.15 moles
calculation
moles of carbon = moles of heptane × number of C atom
number of C atom in heptane = 1 ×7 = 7 atoms
moles is therefore = 21.45 moles × 7 =150.15 moles
Answer: The number of moles of carbon atom that the given amount of heptane is 150.15 moles
Explanation:
We are given:
Moles of heptane = 21.45 moles
The chemical formula for heptane is [tex]C_7H_{16}[/tex]
1 mole of heptane contains 7 moles of carbon atom and 16 moles of hydrogen atom
So, 21.45 moles of heptane will contain [tex](7\times 21.45)=150.15moles[/tex] of carbon atom
Hence, the number of moles of carbon atom that the given amount of heptane is 150.15 moles
