6pints 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
b. 15
c. 14
d. 13
e. 12
am i correct by saying 15?

The percentage alcohol in the new solution is : 16%(A)

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. Concentration shows the amount of solute in a unit of the amount of solvent.

Molarity (M)

Molarity shows the number of moles of solute in every 1 liter of solution.

Where

M = Molarity

n = Number of moles of solute

V = volume of the solution

MIXING SOLUTIONS

Molarity of the mixture of 2 solutions:

Vm Mm = V1. M1 + V2. M2

so that:

where :

Mm = Mixed molarity (M)

Vm = V1 + V2 = mixed volume (ml)

6 pints of a 20 percent solution of alcohol in water are mixed with 4 pints of a 10 percent alcohol in water solution.

V1=6 pints = 2.83906 liters, and concentration M1 =20% = 0.2

V2=4 pints = 1.89271 liters, M2=10% = 0.1

Vm = 2.83906 + 1.89271 = 4.73177 Liters

answer4 to the second power is 16

and 4 to the third power is 64,

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
