Question

I find it hard to solve this please help me guys :(

1. The color changes of a chemical indicator requires an overtitration of 0.04 mL. Calculate percent relative error if the total volume of the titrant is: a) 50.00 mL b) 25.00 mL c) 10.00 mL d) 40.0 mL

Answer 1

the percentage of something is always the part over the total times 100
(part/Total) x 100

if you get $25 discount in a regular price that was $70, what was the discount?
(25/70) x 100 =35.7 %

In the case of your problem that 0.04ml is the part and the 50.00mL is the total
(0.04mL/50.00mL) x 100 = %

I think you will be able to figure out the rest of the problem
