Questions and Answers

What is another name for relative density?

  • Specific gravity (correct)
  • Density ratio
  • Comparative mass
  • Density coefficient

    • How is relative density calculated?

  • Relative Density= Density of Reference Substance + Density of Reference Substance
  • Relative Density= Density of Reference Substance - Density of Reference Substance
  • Relative Density= Density of Reference Substance x Density of Reference Substance
  • Relative Density= Density of Reference Substance/Density of Reference Substance (correct)

    • What does a relative density greater than 1 indicate?

  • The substance has equal density to the reference substance
  • The substance has no relation to the reference substance
  • The substance is denser than the reference substance (correct)
