Answer : The volume of the hydrogen at STP is, 36.8 mL
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 751 torr
= final pressure of gas at STP = 760 torr
= initial volume of gas = 40.0 mL
= final volume of gas at STP = ?
= initial temperature of gas =
= final temperature of gas at STP =
Now put all the given values in the above equation, we get:
Therefore, the volume of the hydrogen at STP is, 36.8 mL
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:
