In a tritation 25cm3 of 0.200mol/dm3 NaOH solution is exactly neutralized
by 22.70 cm3 of a dilute solution of HCl.
1.calculate the concentration of HCl

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

c8h10 is your answerr

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
