a solution made from 35 mL of ethanol and 65 mL of water produces by what percent concentration of volume
To determine the percent concentration by volume of a solution made from 35 mL of ethanol and 65 mL of water, we need to calculate the ratio of the volume of ethanol to the total volume of the solution, and then multiply it by 100.
First, add the volumes of ethanol and water to find the total volume of the solution:
35 mL (ethanol) + 65 mL (water) = 100 mL (total volume)
Next, calculate the ratio of the volume of ethanol to the total volume of the solution:
(35 mL / 100 mL) × 100 = 35%
Therefore, the solution made from 35 mL of ethanol and 65 mL of water has a concentration of 35% ethanol by volume.
To calculate the percent concentration of volume, we need to determine the volume of ethanol in the solution.
Step 1: Add the volume of ethanol and water: 35 mL + 65 mL = 100 mL
Step 2: Calculate the volume percentage of ethanol by dividing the volume of ethanol by the total volume and multiplying by 100:
(35 mL / 100 mL) x 100 = 35%
Therefore, the solution made from 35 mL of ethanol and 65 mL of water has a 35% concentration of volume.
