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.
