In what proportion should 95 percent percent alcohol be mised with 30 percent percent alcohol to make 70 percent percent?
x = volume of 95% y = volume of 30% so (x+y) is volume of 70% 0.95 x + 0.30 y = 0.70(x+y) 0.95 x + 0.30 y = 0.70x + 0.70y 0.25x = 0.40y x/y = 0.40/0.25 = 8/5 for every 8 volumes of 95% mix in 5 volumes of 30%the volumes can be ml, liters, cups, pints etc.

Does hand sanitizer freeze?
There are different hand sanitizer formulations. Look for the active ingredient. If the label says "Ethyl Alcohol" "Isopropanol" or "Methyl Alcohol", you can be confident that the hand sanitizer will only freeze at a very low temperature (-174 degrees F.). Keep in mind that other ingredients may begin to freeze before the alcohol will. Hand sanitizers based on other active ingredients may freeze at temperatures as high as 30 degrees F.
