<h2>
Answer: 8.93 g/cm³</h2>
<h3>
Explanation:</h3>
Density = mass ÷ volume
= 217.0 g ÷ 24.3 cm³
= 8.93 g/cm³
<h3>∴ the unknown sample of mass 217.0 grams and volume of 24.3 cm³ has a density of 8.93 g/cm³.

Photosynthesis is the process by which CO₂ is converted to an organic compound. The complete reaction is as follows;
6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂
stoichiometry of CO₂ to C₆H₁₂O₆ is 6:1
For 1 mol of C₆H₁₂O₆ to be formed - 6 mol of CO₂ is required
Therefore for 3.21 mol of C₆H₁₂O₆ to be formed - 6 x 3.21 mol of CO₂ required
Number of moles required are - 19.26 mol of CO₂
