Popular Problem-Solving Workflows
- •When diluting concentrated acids, always add acid to water (never water to acid) to prevent thermal splashing.
- •Check that volumetric units match on both sides of the C₁V₁ = C₂V₂ equation before solving.
Molarity tells you how crowded the molecules are in a liquid, just like how sweet a glass of lemonade is based on how many spoons of sugar you stirred in!
