Question 1
A student mixes 5 moles of glucose (C₆H₁₂O₆) in water. Calculate the mass of glucose used. (C₆H₁₂O₆ has a molar mass of 180.18 g/mol.)
💡 Hint: Use the definition of molar mass.
Question 2
If 2 moles of sulfuric acid (H₂SO₄) react with sodium hydroxide (NaOH), what mass of NaOH is required? (The molar mass of NaOH is 40.00 g/mol and the reaction is 2 H₂SO₄ + 2 NaOH → 2 Na₂SO₄ + 2 H₂O)
💡 Hint: Refer to the balanced chemical equation.
