Answer:
4 M
Explanation:
Molarity can be represented by the following ratio:
Molarity = moles / volume (L)
Since you have been given both the mass and volume, you can plug the values into the equation and solve for molarity.
Molarity = moles / volumes
Molarity = 2.0 moles / 0.50 L
Molarity = 4 M
The second stage of photosynthesis also called Calvin stage produces glucose
Answer:
11.3 g.
Explanation:
Hello there!
In this case, since the combustion of butane is:

Thus, since there is a 1:5 mole ratio between butane and water, we obtain the following mass of water:

Therefore, the resulting mass of water is:

Best regards!
Answer:
60%
Explanation:
M(NH4NO3) = 2*14 +4*1 +3*16 = 80 g/mol
M(3O) = 3*16 = 48 g/mol
(48/80) *100 % =60% oxygen by mass.
