### Hydrogen Cyanide Toxicity Calculation#### Problem ContextHydrogen cyanide (HCN) is a poisonous gas. The lethal dose is approximately **330 mg HCN per kilogram of air** when inhaled.#### Part A**Question:**Calculate the amount of HCN that gives the lethal dose in a small laboratory room measuring **12 x 14 x 8 ft**. The density of air at 25°C is **0.00118 g/cm³**.**Instructions:**Express your answer using two significant figures.**Answer Submission Section:**- Input field for answer (m = ___ g)- Submit button- Previous Answer, Request Answer buttons- Feedback showing an incorrect attempt with 4 remaining attempts: - "Incorrect; Try Again: 4 attempts remaining"#### Part B**Question:**If HCN is formed by reaction of NaCN with an acid such as H₂SO₄, what mass of NaCN gives the lethal dose in the room? The reaction is:\[ 2NaCN_{(s)} + H₂SO₄_{(aq)} → Na₂SO₄_{(aq)} + 2HCN_{(g)} \]**Instructions:**Express your answer using two significant figures.**Answer Submission Section:**- Input field for answer (m = ___ g)- Submit button- Request Answer button### Additional Notes:1. **Units Conversion:** - Convert room dimensions from feet to centimeters. - Convert air density from g/cm³ to lb/ft³ if necessary.2. **Lethal Dose Calculation:** - Calculate the room volume. - Determine the mass of air in the room. - Use the given lethal dose to find the required mass of HCN.3. **Stoichiometry:** - Use the balanced chemical reaction to determine the mass of NaCN needed to produce the calculated mass of HCN.### Graphs and DiagramsThere are no graphs or diagrams included in this problem set.
