Answer:
6.49g
Explanation:
Let's consider the balanced reaction for photosynthesis.
6 CO₂ + 6 H₂O = C₆H₁₂O₆ + 6 O₂
We can establish the following relations:
- 1 mole of CO₂ has a mass of 44.01 g (MW 44.01)
- The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1.
- 1 mole of C₆H₁₂O₆ has a mass of 180.16 g/mol.
The mass of glucose produced by the reaction of 9.51 g of carbon dioxide is:

When carbon bonds with 4 hydrogen atoms which is methane having sp3 structure so it is tetrahedral. electricity is conducted by electrons so graphite conducts by free and delocalised sea of electrons.
The relation between density, mass and volume is

1) to calculate = volume
given:
Density = 0.0915 g/ mL
mass = 17.7 grams
formula used:

Thus
Volume 
Answer: 193.44 mL
2) the mass of sample will be

Answer: 7 g
B is correct
salt lowers the freezing point of water (colligative property) by lowering the interaction and intermolecular forces between water molecules
