Certainly! Let’s calculate the number of molecules in 0.00506 moles of H₂O step-by-step.
1. Understand the Problem:
- We are given a certain number of moles of water (H₂O) and need to find out how many individual water molecules this quantity represents.
2. Given Data:
- Number of moles of H₂O = 0.00506
3. Avogadro's Number:
- Avogadro's number is \(\(6.02214076 \times 10^{23}\)\) molecules per mole. This number tells us how many molecules are present in one mole of a substance.
4. Calculation:
- To find the number of molecules, we multiply the number of moles by Avogadro's number:
\(\[
\text{Number of molecules} = \text{Number of moles} \times \text{Avogadro's number}
\]\)
- Plug in the values:
\(\[
\text{Number of molecules} = 0.00506 \times 6.02214076 \times 10^{23}
\]\)
5. Result:
- After performing the multiplication:
\(\[
\text{Number of molecules} \approx 3.0472032245600003 \times 10^{21}
\]\)
Therefore, there are approximately \(\(3.0472032245600003 \times 10^{21}\)\) molecules in 0.00506 moles of H₂O.
