A chemist has three different acid solutions. The first acid solution contains 25 % acid, the second contains 35 % and the third contains 80 % . He wants to use all three solutions to obtain a mixture of 40 liters containing 55 % acid, using 2 times as much of the 80 % solution as the 35 % solution. How many liters of each solution should be used?

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
