Quick Answer: What volume of ethyl alcohol and water must be mixed together to prepare 250 ml of 50?

What volume of ethyl alcohol and water must be mixed together to prepare 250 mL of 60 by volume?

60% by volume of alcohol solution means,each 100 ml of solution will have 60 ml ethyl alcohol. hence in a 250ml solution of 60% by volume of alchohol and water,alcohol should be 150 ml and water should be 100 ml.

What volume of rubbing alcohol is required to add in water to prepare 250 mL of 70?

You would add enough water to 175 mL of rubbing alcohol to make a total of 250 mL of solution.

What volume of ethyl alcohol and water must be mixed together?

Hence ethyl alcohol needed is 150ml and water 100ml.

How many mL of ethanol should be added to 250ml of water?

Answer Expert Verified. The required value of x is 200 ml.

What is the volume of ethyl alcohol?

Example: when 52 ml pure ethanol is mixed with 48 ml of water a volume of 96.3 ml is obtained instead of 100 ml.

Ethanol concentration table: what is the percentage by volume or weight?

Concentration of ethanol by weight (w/w) Concentration of ethanol by volume (v/v)
62.4% (w/w) 70.0% (v/v)
65.0% (w/w) 72.4% (v/v)
70.0% (w/w) 77.0% (v/v)
73.5% (w/w) 80.0% (v/v)

How much water should be mixed with 25 ml of alcohol so as to obtain 12% alcohol solution?

So w need to add 88 ml of water to make it a 12% alcohol solution.

How much water should be mixed with 12 mL of alcohol so as to obtain 12% alcohol solution?

Answer: 88 milliliter water should mix in 12 ml of alcohol so as to obtain 12% of alcohol solution.

How much 95% ethanol do you need to make a 600 mL solution of 70% ethanol?

For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol. This works for any dilution and all that is required is a large enough graduated cylinder.

What is the percent by a solution formed by mixing 25 mL of isopropanol with 45 mL water?

What is the percent by volume of a solution formed by mixing 25 mL of isopropanol with 45 mL of water? 35.7% isopropanol solution.

How do you dilute 95% alcohol to 75%?

To replace 1 liter of 95% alcohol we have to use 1.26 liters of 75% alcohol. We need more 75% alcohol because water was added to 95% alcohol to bring it down to make the 75% version.

How many ethyl alcohol is present in a 250 mL?

Add water to the ethanol and measure the volume of the resulting solution. For the example, the water and ethanol combine, forming a solution with a volume of 250 mL. Divide by the conversion factor for milliliters to liters. The example solution contains 0.17 moles of ethanol in 250 mL of solution.

Why does ethanol and water have less volume?

When water and ethyl alcohol mix, several forces come into play. First, between the water and ethyl alcohol is strong hydrogen bonding that draws the different molecules close together. … The 2 different molecules pack closer together than in pure solution, resulting in a reduction of volume.
