If 45.0 ml of 0.25 M sodium chloride solution is diluted to a
final volume of 170.0 ml what is the concentration of the new
solution ?
I know the answer is A but I don’t know how to get to the
right answer :(

How did he get the electric feild? I could not approch the final
answer !
The figure shows 5 charged objects made of plastic and a neutral metal disc. The cross section of a closed Gaussian Surface S is indicated. What is the electric flux through the surface S if q1 = q4 = 3.1 mu C, q2 = q5 = -6.9 mu C, and q3 = -2.3 mu C?
How do you find the initial concentration if you are only
given the initial volume and final volume? I have tried using the
V(i) x C(i) =V(f) x C(f) equation but it needs at least 3 figures
so I'm a bit lost right now.

quite understand how to get to the final answer, if you can, please
explain steps!
Before the collision Cart A Cart B Cart A, with an inertia ma, and Cart B, with an inertia ma, are on a level track with negligible friction. In the Earth reference frame, Cart A, initially moving to the right with a velocity VEAj collides with Cart B, initially moving to the left with a velocity Vedi as shown...
