Mole Concept
How many molecules of water are present in 0.25 mol of H2O?
Select the correct option:
Solution
- Avogadro's Number (NA): 1 mol=6.022×1023 particles.
- Calculate Molecules:
- Total molecules=Moles×NA
- Total molecules=0.25 mol×6.022×1023 mol−1
- Total molecules≈1.5055×1023.
- Scientific Notation: Rounding correctly for the options gives 1.5×1023 molecules.
