Final answer:
The mass of each component in the solution is Methanol: 40 g, Ethanol: 40 g, and Water: 20 g.
Step-by-step explanation:
To determine the mass of each component in the solution, we first need to calculate the mass of methanol, ethanol, and water in the solution. Let's assume we have a 100 g solution. 40% of methanol means we have 40 g of methanol. Similarly, 40% of ethanol means we have 40 g of ethanol, and 20% of water means we have 20 g of water. Therefore, the mass of each component is:
- Methanol: 40 g
- Ethanol: 40 g
- Water: 20 g
