How do you make 70\% alcohol?
Add 350 mL of 100 percent isopropyl alcohol to a 500 mL graduated cylinder. Ensure that the measurement is read at eye level with the meniscus, the bottom of the curved liquid, at 350 mL. Add an additional 150 mL of water to the graduated cylinder for a total volume of 500 mL, again measured at eye level.
How will you prepare 600ml of 30 alcohol from 60\% alcohol?
Answer: Quantity required = 20parts of 60\%+10 parts of 50\%+ 1 …
How much of pure alcohol has to be added to 500 mL of a solution that contains 10\% alcohol in order to change the concentration of alcohol in the mixture of 20 \%?
∴ The required result will be 62.5 ml.
How do you make 90 alcohol?
take 785 ml of 90\% v/v ethanol, or 730 ml of 95\% v/v ethanol, or 707 ml of 99\% v/v ethanol; add distilled or filtered water to make up a volume of 1 litre; leave to cool and top up with water again to bring the volume back to 1 litre (mixing water and ethanol together produces a reaction whereby volume is reduced).
How much alcohol must be added to 500 ml of 60\% solution to make its strength 75\%?
Answer: 125ml should be added to make its strength75\%.
How do you make a 60 alcohol solution?
All you need are 2 ingredients: Isopropyl Rubbing Alcohol + Aloe Vera Gel. (If you’re allergic to aloe or just can’t find any, you can use vegetable glycerin instead). All you need to know is the right proportion of isopropyl rubbing alcohol to aloe vera gel to make it at least 60\% alcohol.
How do you make 95\% alcohol to 75?
To replace 1 liter of 95\% alcohol we have to use 1.26 liters of 75\% alcohol….This means that you have 75\% of pure alcohol and 25\% of water:
- 0.75 x 1000 = 750 ml.
- This is the amount of pure alcohol.
- 0.25 x 1000 = 250 ml.
- This is the amount of water.
How much alcohol must be added to 500 ml of a 60 solution to make its strength 75?
How much pure alcohol should be added to 600 ml of a 15\% solution to make its strength 32\%?
Therefore, 100 mL of alcohol should be added to make the strength 32\%. This is the required answer.
How do you calculate 60\% alcohol from 100ml?
We can calculate any amount by multiplying the 100 ml of desired alcohol by a corresponding factor. For example we need 750 ml of 60\% alcohol. Our factor is 7.5 as 7.5 x 100 ml comes to 750 ml. 7.5 x 80 + 7.5 x 20 = 600 + 150 = 750 ml of 60\% alcohol.
How much water do you add to dilute alcohol?
To calculate the amount of water to add to dilute your alcoholic concentration, multiply the amount of spirits you have by (strong/weak) – 1. For example, if you want to dilute 5L of 80\% alcohol down to 50\%, you will need to add 5 – ( ( 50 x 5 ) / 80 ) = 1.875L of water is required. Related Calculators:
How do you make a 70\% solution of ethanol?
For example, a 70 \% (v/v) solution of ethanol can be prepared by dissolving 70 mL of 100\% (i.e., 200 proof) ethanol in a total solution volume of 100 mL. Other factors may also be important when deciding on the type of percent solution to prepare.
How much alcohol can I replace 75\% with 60\%?
V2 = 0.75 x 1/0.60 V2 = 0.75/0.60 The answer says that you can replace 1 liter of 75\% alcohol with 1.25 liter of 60\% alcohol. However, you want to know how much water should be added to 75\% alcohol. The amount of alcohol has not changed.
