In a 66.0-g aqueous solution of methanol, CH4O, the mole fraction of methanol is 0.290. What is the mass of each component? g
1 answer:
Answer:
23.84g CH30H
32.81g H2O
Explanation:
We will be using the definition of mole fraction to determine the relationship between the number of moles of methanol,
CH3OH , and the number of moles of water.
But mole fraction gives the ratio between the number of moles of a component i of a solution to the total number of moles present in that solution.

Answer: The balanced equation is .
Explanation:
The given reaction equation is as follows.
Number of atoms present on reactant side are as follows.
- Li = 1
- H = 1
= 1
Number of atoms present on product side are as follows.
- Li = 1
- H = 2
To balance this equation, multiply Li by 2 and by 2 on reactant side. Also, multiply
by 2 on product side.
Hence, the equation can be rewritten as follows.
Now, number of atoms present on reactant side are as follows.
- Li = 2
- H = 2
Number of atoms present on product side are as follows.
- Li = 2
- H = 2
As there are same number of atoms on both reactant and product side. Hence, the equation is now balanced.
Thus, we can conclude that the balanced equation is .
