📐Step-by-Step Mathematical Derivation

Given ➔ Formula ➔ Solve

1. Given Quantities:

• Compound: H2O

• Molar Mass (M): 18.015 g/mol

• Known Input: 36 g

2. Governing Formula:

n = m / M ; N = n × N_A

3. Substitute Values:

n = 36 g / 18.015 g/mol

4. Calculated Result:

Moles = 1.9983 mol ; Mass = 36 g

5. Chemical Interpretation:The sample contains approximately 1.9983 moles of H2O, equivalent to 12.03 × 10²³ individual molecules.

🔬Why is the Mole So Big?

Individual atoms are so tiny that a single drop of water contains over a billion trillion molecules!

The mole ($6.022 \times 10^23$) serves as the chemist's "dozen"—a convenient bridge between single-atom masses in atomic mass units (amu) and laboratory masses measured in grams.
