How many ounces of a 1212% alcohol solution must be mixed with 33 ounces of a 2020% alcohol solution to make a 1414% alcohol solution? the number of ounces of the 1212% alcohol solution that needs to be mixed is nothing ounces. (simplify your answer.)

99 ounces of the 12% alcohol solution that needs to be mixed.

Explanation:

Let the volume of 12% alcohol solution be x.

Volume of alcohol added = 0.12 x

Volume of 20% alcohol solution  = 33 ounces

Volume of alcohol in 20% of alcohol solution =

Total volume of alcohol after addition = (0.12 x +6.6) Oz

Total volume of alcohol solution after addition = x + 33 Oz

Percentage of alcohol solution after addition = 14%

Also ,Total volume of alcohol after addition =

Solving for x :

x = 99 ounces

99 ounces of the 12% alcohol solution that needs to be mixed.

sry but any answer choices

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
