Answer:
Concept: Chemical Analysis
- You need to start by graphing the data and then analyzing it.
- We can see that the horse has a distance in meters of 980 at the end of the 10 seconds hence it is the fastest.
- The horse line has a linearly representation, while the alternate line has parabolic tendencies towards the end. The steeper line indicates a faster change in time or velocity which results in a greater distance traveled indicating that the horse is faster.
- *I have confidence you can graph that*
M1v1=m2v2
m2=(m1v1)/v2
Where m is the molarities and v is the volumes
<span>m2=(25.0*0.500)/53.5
m2=12.5/53.5
m2=0.2336
by rounding off:
m2=0.234 M
so the answer is C: 0.234 M</span>
