Respuesta :
the answer would be A. Take .20 multiply it by 6 because there are 6 pints with that concentration, and take .10 and multiply it by 4. Add the two together. Take the number that you had just got and divide it by because if you take the amount of pints in total (10). You end up with 1.6 and you divide it by 10 because of the pints to get .16 or 16%
6 pints of a 20 percent solution of alcohol in water are mixed with 4 pints of a 10 percent alcohol in water solution. The percentage alcohol in the new solution is a. 16%
Explanation:
Alcohol is a depressant drug found in all alcoholic drinks such as wine, beer and spirits and is usually produced by fermentation. The reactions of alcohol in the body depends on the content consumed and how quickly it consumed.
6 pints of a 20 percent solution of alcohol in water are mixed with 4 pints of a 10 percent alcohol in water solution. The percentage alcohol in the new solution is:
The substance concentration can be expressed in quantities such as moles, percent (%) weight / volume), molarity, molality, parts per million (ppm) or mole fraction. Concentration is the amount of solute in a unit of the amount of solvent
Total Volume
6 + 4 = 10 pints
The volume of alcohol in final solution:
20% * 6 = 1.2 pints
10% * 4 = 0.4 pints
Total pints = 1.2 pints + 0.4 pints = 1.6 pints of alcohol in 10
Percentage = (1.6/10) * 100 = 16%
Therefore the answer is a. 16%
