convert 1.75 × 1024 atoms of carbon to moles of carbon.
Number of C atoms = moles of C atoms x 6.02x 10^23. Therefore moles of C atoms = 1.75x10^24 / 6.02x 10^23 = 2.90 moles
Answer: The number of moles of carbon is 2.90 mol.
Explanation:
We are given:
Number of atoms of carbon = \(1.75\times 10^{24}\)
According to mole concept:
\(6.022\time 10^{23}\) number of atoms are contained in 1 mole of an element.
So, \(1.75\times 10^{24}\) number of atoms will be contained in = \(\frac{1}{6.022\times 10^{23}}\times 1.75\times 10^{24}=2.90mol\) of carbon.
Hence, the number of moles of carbon is 2.90 mol.
