To calculate the number of molecules in 6.00 moles of H2S (hydrogen sulfide), we use Avogadro's number, which is \(6.022 \times 10^{23}\) molecules per mole. This number represents the number of particles in one mole of a substance.

Here are the logical steps to calculate the number of molecules:

Step 1: Write down the number of moles of H2S given, which is 6.00 moles.

Step 2: Multiply the number of moles by Avogadro's number to get the number of molecules: \[ \text{Number of molecules} = \text{Number of moles} \times \text{Avogadro's number} \]

Step 3: Perform the calculation:

\[ \text{Number of molecules} = 6.00 \, \text{moles} \times 6.022 \times 10^{23} \, \text{molecules/mole} \] \[ \text{Number of molecules} = 36.132 \times 10^{23} \, \text{molecules} \]

Step 4: Write down the result in a proper scientific notation, if necessary. In this case, the number is already in the correct format.

So, 6.00 moles of H2S contain \(36.132 \times 10^{23}\) molecules.
