Questions and Answers

What is the derived unit for measuring force?

  • m/s
  • G/cm3
  • Joule
  • kg·m/s2 (correct)

    • How many grams are in 0.572 moles of glucose (C6H12O6)?

  • 90 g
  • 102.96 g (correct)
  • 180 g
  • 72 g

    • What is the formula used to convert moles to grams?

  • No. of grams = no. of moles × molar mass (correct)
  • No. of grams = molar mass/no. of moles
  • No. of grams = no. of moles/molar mass
  • Molar mass = no. of grams/no. of moles
