Isopropyl alcohol has a rather strong alcohol smell. If you were to smell regular alcohol and smell 70% Isopropyl alcohol you would have the same smell.
However, there is no general way to explain it other than a strong bitter and sometimes sweet smell. It depends on solely your olfactory membranes. Smell's are after all different to everyone.

70% alcohol has been found to be more effective in killing microbes.Higher and lower concentration may not be as effective.90% alcohol coagulate proteins in contact.suppose 90% alcohol is poured over one celled organism,the alcohol penetrate the cellwall of the organism.the coagulated protein would then prevent the alcohol further from the cell and no more coagulation then take place.now,if 70% alcohol is added into one celled organism.The diluted alcohol also coagulates the protein, but at a slower rate,so that it penetrates all the cell before coagulation.Then all the cell coagulated and the organism died.
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.
I personally just put some 65% ethyl alcohol hand sanitizer on mine, and it burnt really bad for a minute or two. 70% probably won't kill you. Feelin' so fresh!
Yes, it is.
70%
The weight will depend on how much of the substance there is.
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.

I believe it's ethyl alcohol. Also I think rubbing alcohol is 70% isopropyl alcohol and 30% water.. Hope i helped!Rubbing alcohol is a solution of 70% isopropyl alcohol (also called isopropanol or 2-propanol), and 30% Deionized water.Ethyl alcohol is something entirely different.Note that there are also different solutions of Isopropyl alcohol that can also be used for disinfecting and first aid, but Rubbing alcohol is the household name for the 70% Isopropyl alcohol solution.

Assuming it is 90% by volume isopropyl alcohol, then 70 ml of rubbing alcohol would contain 63 mls of isopropyl alcohol.
Rubbing alcohol is 70% isopropyl alcohol, so you wouldn't use it since it contains some water. Use 99% isopropyl alcohol instead.
Rubbing alcohol is called 2-propanol or isopropyl alcohol.
It is prepared from a special denatured alcohol solution and contains approximately 70 percent by volume of pure, concentrated ethanol (ethyl alcohol) or isopropanol (isopropyl alcohol), so approximately 35 mL in a 50mL bottle.
2/3 of 70% and 1/3 of 10%
