Question

how many moles of s are in 2.4 x 10^{24} atoms of sulfur?
\frac{2.4 x 10^{24} atoms s}{6.02 x 10^{23} atoms s}
4.0 x 10^{46} moles s
4.0 moles s
4.0 x 10^{1} moles s
1.0 mole s

Explanation:

Step1: Set up the conversion

We know that \(1\) mole of any substance contains \(6.02\times10^{23}\) atoms (Avogadro's number). So, to convert atoms of \(S\) to moles of \(S\), we use the conversion factor \(\frac{1\space mole\space S}{6.02\times 10^{23}\space atoms\space S}\).
The formula is \(n=\frac{N}{N_A}\), where \(n\) is the number of moles, \(N\) is the number of atoms, and \(N_A = 6.02\times10^{23}\space atoms/mol\). Here, \(N = 2.4\times 10^{24}\space atoms\) of \(S\).

Step2: Calculate the number of moles
