6. potassium hydrogen phthalate (khp, khc8h4o4) is also a good primary standard. 20 ml of naoh was titrated with 0.600 m khc8h4o4 solution. the data was graphed and the equivalence point was found when 15.5 ml of the standard 0.600 m khp solution was added. the reaction equation is: a. what is the molar ratio of naoh: khc8h4o4? b. what is the molarity of the naoh solution?

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
