80ml of methyl alcohol water are mixed to give a solution that has a final volume of 154ml. What is the concentration of the solution expressed as percent by volume methyl alcohol?
% v/v means (volume solute/total volume)*100 = ? = (80/154)*100 = ?
0.5195
To find the concentration of the solution expressed as a percent by volume of methyl alcohol, you need to determine the volume of methyl alcohol in the solution and calculate the percentage.
Given:
Volume of methyl alcohol = 80 ml
Final volume of the solution = 154 ml
To find the volume of water in the solution, subtract the volume of methyl alcohol from the final volume of the solution:
Volume of water = Final volume of solution - Volume of methyl alcohol
Volume of water = 154 ml - 80 ml
Volume of water = 74 ml
Now, you can calculate the percentage of methyl alcohol in the solution:
Percentage by volume of methyl alcohol = (Volume of methyl alcohol / Final volume of solution) * 100
Percentage by volume of methyl alcohol = (80 ml / 154 ml) * 100
Percentage by volume of methyl alcohol ≈ 51.95%
Therefore, the concentration of the solution expressed as a percent by volume of methyl alcohol is approximately 51.95%.
To determine the concentration of the solution, expressed as percent by volume of methyl alcohol, we need to calculate the volume of methyl alcohol in the solution and then express it as a percentage of the total volume.
Given:
Initial volume of methyl alcohol = 80 ml
Final volume of the solution = 154 ml
To find the volume of methyl alcohol in the solution:
Volume of water = Final volume - Initial volume
= 154 ml - 80 ml
= 74 ml
Volume of methyl alcohol = Initial volume = 80 ml
Total volume of the solution = Final volume = 154 ml
Now, to calculate the concentration as percent by volume:
Concentration of methyl alcohol = (Volume of methyl alcohol / Total volume of the solution) x 100
Plugging in the values:
Concentration of methyl alcohol = (80 ml / 154 ml) x 100
Concentration of methyl alcohol = 0.5195 x 100
Concentration of methyl alcohol ≈ 51.95%
Therefore, the concentration of the solution, expressed as percent by volume of methyl alcohol, is approximately 51.95%.
