Hello,
In this case, for the mole fraction of methanol we use the formula:
Thus, we compute the moles of both water (molar mass 18 g/mol) and methanol (molar mass 32 g/mol):
Hence, mole fraction is:
Next, mass percent is:
And the molality, considering the mass of water in kg (0.185 kg):
Regards.
It's depending on what size of the tree it is. For example, if the tree is large it will block most of the water that runs through. If the tree is small it shouldn't do as much besides block a little amount of water and it will probably go down stream.
This is based on my thinking
Answer:
B. Identify solutions to the problem.
Explanation:
In the case described above, the engineer has already designed and attempted to manufacture a prototype for the process. The design of the process must have also been carefully researched and planed.
However, he identified the problem of low yield and is now working towards identifying solutions to the problem. One option he seeks to explore according to the question is to change the catalyst used in the reaction.
