Transcribed Image Text:

20.5mL of methanol, CH40 (MM = 32.042), is mixed with 88.5mL of water (MM = 18.015) at 25°C. The final volume of solution is 106.2mL. The densities of methanol and water are 0.782g/mL and 0.997g/mL, respectively. Calculate the % mass of methanol in the solution. 20.5mL of methanol, CH40 (MM = 32.042), is mixed with 88.5mL of water (MM = 18.015) at 25°C. The final volume of solution is 106.2mL.
