Which has more alcohol in it a solution of one percent by volume or one percent by weight?
One percent by weight. Alcohol has a density of less than water, so 1 g of alcohol is more than 1 mL.

60 to 80 percent to make clean, ethical kills , anything less than 50 percent is unethical and may not kill the animal it may just run away and suffer
Why is alcohol 70 percent?
Isopropyl rubbing alcohol is usually around 70% (by volume) because this is the optimum concentration for its action as a disinfectant. At lower concentrations it is not as effective. However at higher concentrations its effectiveness declines because of the way in which it works. Alcohol kills cells in the target organisms by causing the coagulation of proteins which it contacts. If very strong alcohol is used then it penetrates the cell wall of the organism and coagulates the proteins which are immediately inside the cell wall and this mass of coagulated protein protects the inner parts of the cell from the alcohol. Then, if conditions improve, the cell can recover. Alcohol which is less concentrated works in the same way but because it coagulates the proteins more slowly, more of the alcohol is able to penetrate deeper into the cell and so is more effective in destroying the cell.
What is 10 percent less of125?

What is the difference of 50 percent less 46.67 percent?
50% less 46.67% = 3.33%

Can Copper nitrate be used to kill algae in pool water?

Why 100 percent alcohol doesn't kills bacteria?
100 percent alcohol, also known as absolute alcohol, denatures and dehydrates bacteria, preventing their growth and reproduction rather than directly killing them. Water is needed to facilitate the bacteria-killing action of alcohol, so using 100 percent alcohol may not be as effective as lower concentrations when combating bacteria.
Why is pure alcohol more dangerous than adulterated alcohol?
Pure alcohol is far more dangerous than adulterated alcohol because pure alcohol has one hundred percent alcohol in comparison to aldulterated alcohol which is less than 100 percent.

Is it safe to put rubbing alcohol on a small open wound?
YesBut it will hurt like hell. Rubbing alcohol will dehydrate the tissue around the wound and stretch it besides which can sometimes slow healing. If available, hydrogen peroxide makes for a better clensing agent. Edit: Betadine (Povidone Iodine) is another - less painful - alternative.
Why is 70 percent isopropyl alcohol more expansive than 40 percent isopropyl alcohol?
It is difficult and expensive to refine anything to 100% purity. Best to use 70% as it is just as effective and cost a whole lot less.
Why 70 percent alcohol is used as disinfectant?
A 70% alcohol solution is effective as a disinfectant because it has the optimal concentration to penetrate bacterial cells and denature proteins, effectively killing them. Higher concentrations of alcohol can evaporate too quickly and be less effective at killing bacteria, while lower concentrations may not be as potent.
Does miller 64 have less alchol than other beers?
Yes, it has much less alcohol, only 2.8 percent.
How does salt sanitize?
The sodium and chloride make cells unable to function. This kills bacteria, which are much less able to handle the effects, but not body cells that can.
