Hey, good to see you again. To calculate the mass of sodium hydroxide produced, follow these steps: Step 1: Calculate the molar mass of sodium (Na). The atomic mass of Na is given as 23. Molar mass of Na = 23 \, g/mol Step 2: Calculate the number of moles of sodium (Na) given. Given mass of Na = 2.3 \, g. Moles of Na = Mass of NaMolar mass of Na = 2.3 \, g23 \, g/mol = 0.1 \, mol Step 3: Determine the mole ratio between Na and NaOH from the balanced equation. The balanced equation is: 2Na(s) + 2H_2O(l) → 2NaOH(aq) + H_2(g) From the equation, 2 moles of Na produce 2 moles of NaOH. The mole ratio of Na : NaOH is 2:2, which simplifies to 1:1. Therefore, moles of NaOH produced = moles of Na reacted. Moles of NaOH = 0.1 \, mol Step 4: Calculate the molar mass of sodium hydroxide (NaOH). Atomic masses: H = 1, O = 16, Na = 23. Molar mass of NaOH = Na + O + H = 23 + 16 + 1 = 40 \, g/mol Step 5: Calculate the mass of sodium hydroxide (NaOH) produced. Mass of NaOH = Moles of NaOH × Molar mass of NaOH Mass of NaOH = 0.1 \, mol × 40 \, g/mol = 4.0 \, g The calculated mass of sodium hydroxide is 4.0 \, g. Comparing this to the given options: A 0.40g B 0.80g C 4.00g D 8.00g The correct option is C. The final answer is C Send me the next one 📸
