How much water should be mixed with 20ml of alcohol so as to obtain 20% alcohol solution?

make it 20% solution means alcohol should be 20% in solution. so 80 ml water must be added.

How much water should be added to 12 ml of 12 alcohol solution to reduce the concentration to 6?

add 12 ml will reduce the concentration by 2. It works intuitively, you have the same amount of alcohol but in doubl the volume, the concentration is then 50%. Add 12 ml of water and the concentration will be reduced to 6% alcohol.

Why is 70 alcohol better than 40?

Even though you may think the higher concentration is more effective, experts say 70% is actually better for disinfecting. It has more water, which helps it to dissolve more slowly, penetrate cells, and kill bacteria. The disinfecting power of rubbing alcohol drops at concentrations higher than 80%-85%.

What is the percent by volume of isopropanol?

For example, when you buy isopropanol at the store (rubbing alcohol), you’ll notice that it says 70% (vv), which means by volume. This tells you that the solution is 70% isopropanol. So, returning to our rubbing alcohol, 70% (vv) means that for every 100 mL of solution, there are 70 mL of the solute, isopropanol.

What is the chemical formula for ethyl alcohol?

The molecular formula of ethanol is C2H6O, indicating that ethanol contains two carbons and an oxygen. However, the structural formula of ethanol, C2H5OH, provides a little more detail, and indicates that there is an hydroxyl group (-OH) at the end of the 2-carbon chain (Figure 1.1).
