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:

(i) We start by calculating the mass of sugar in the solution:
mass of sugar = concentration × solution mass
mass of sugar = 2.5/100 × 500 = 12.5 g
Then now we can calculate the amount of water:
solution mass = mass of sugar + mass of water
mass of water = solution mass - mass of sugar
mass of water = 500 - 12.5 = 487.5 g
(ii) We use the following reasoning:
If 500 g solution contains 12.5 g sugar
Then X g solution contains 75 g sugar
X=(500×75)/12.5 = 3000 g solution
Now to get the amount of solution in liters we use density (we assume that is equal to 1):
Density = mass / volume
Volume = mass / density
Volume = 3000 / 1 = 3000 liters of sugar solution
Answer:
elliptical galaxy
Explanation
:The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to disappear. The merger of gasses creates new stars, and the new shape becomes more elliptical, globular, or sometimes irregular.
Answer:
moles Ar in 20g = 0.500 mole Ar
Explanation:
moles = grams given / formula weight = 20g / 39.948g·mol⁻¹ = 0.500 mole Ar
