To prepare 100ml of 70% Ethanol, measure 70ml of 95% ethyl alcohol in a graduated cylinder and add 30ml of distilled water. To prepare 100ml of 70% Ethanol, measure 70ml of 95% ethyl alcohol in a graduated cylinder and add 30ml of distilled water.
It is made from absolute ethanol. Use M1V1 =M2V2.
737 ml 95% EtOH + 263 ml d H2O
1/10 part
If the solution is 67% sugar by weight, then take the weight of one gallon of water and multiply by 67%:One gallon of water weighs 8.34 lbs0.67 * 8.34 = 5.59 lbs.
It's not possible to sterilize water with alcohol.
One ounce of UAN 32% Fertilizer to the gallon
120 ounces
A bit over an ounce and a quarter. Specifically, 1.28 oz.
Add 5% water
16 halfpint cartons of water are needed to fill the gallon container
Because the concentration of alcohol is lower; you pay the alcohol not the water.
If the solution is 67% sugar by weight, then take the weight of one gallon of water and multiply by 67%:One gallon of water weighs 8.34 lbs0.67 * 8.34 = 5.59 lbs.
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
It's not possible to sterilize water with alcohol.
16%
You mix the pure alcohol with something else, for example, water.
1.5 gallons of water does that. 1.5 gallons weighs 50% more than 1 gallon. If you reduce it 50%, you have 0.75 gallon, and that weighs less than 1 gallon.
It is usually a mixture of alcohol and water in which 40%, by volume is alcohol.
add water
No, the latter is denser, due to higher water content.
