A chemist is using 357 milliliters of a solution of acid and water. If 13.2 % of the solution is acid, how many milliliters of a
Vilka [71]

Answer:

The quantity of acid in the solution is 47.1 ml

Step-by-step explanation:

Given as :

The quantity of solution of acid and water = 357 millimeters

The percentage of acid in the solution = 13.2 %

Let the quantity of acid in the solution = x ml

<u>So, According to question </u>

13.2 % of the total quantity of acid in the solution = x

I.e x = 13.2 % × 357

Or, x = \frac{13.2}{100} × 357

Or, x = 0.132  × 357

∴  x = 47.124 millimeters

So , The quantity of acid = 47.1 ml

Hence The quantity of acid in the solution is 47.124 ml  Answer

There are 11 candidates for three postions at a restaraunt. One postion is for a cook. The second position is for a food server
LenaWriter [7]

Answer:

165 combinations possible

Step-by-step explanation:

This is a combination problem as opposed to a permutation, because the order in which we fill these positions is not important.  We are merely looking for how many ways each of these 11 people can be rearranged and matched up with different candidates, each in a different position each time.  The formula can be filled in as follows:

₁₁C₃ = \frac{11!}{3!(11-3)!}

which simplifies to

₁₁C₃ = \frac{11*10*9*8!}{3*2*1(8!)}

The factorial of 8 will cancel out in the numerator and the denominator, leaving you with

₁₁C₃ = \frac{990}{6}

which is 165

Problems that require solving the three-dimensional schrödinger equation can often be reduced to related one-dimensional problem
dusya [7]
The wavefunction for a particle in a one-dimension box is a well-known problem, which has as a solution:

Ψ(x) = √(2/l) sin (nπx/l)

When the box has three dimensions, the general solution is simply the multiplication of the solutions for each dimension, therefore:

Ψ(x) = K · sin (n_x·π·x / l) · sin (n_y·π·y / l) · sin <span>(n_z·π·z / l)</span>
