Hi there i am having extreame difficulty doing pre lab homework can i please get help on the questions i have circled down below.

please solve the questions providing detailed

solution so i can take notes and understand and better prepare for an actual lab

note-please provide details as you solve the problems so i can take notes too and learn please solve the questions curcled in red. Its only one red circle

list

*provide the 3 trials for (VOLUME OF KOH USED)in mL.just kindly fill in the 3 blanks and show me how u got it so i can take notes and undersatnd.

*Average volume of NaOH (mL) used

*calculate the concentration the equation is given

*Conclusion

if you have any question pls reach out .Thanks soo much for your cooperation

correct KOH .Im very sorry for the mistake .PLEASE CALCULATE KOH NOT NAOH

Purpose To determine the concentration of a sulphuric acid solution. Materials .burette and stand phenolphthalein pipette and pipette pump small Erlenmeyer flask sulphuric acid (7) Waste beaker 0.3M KOH . funnel Procedure 1. Obtain approximately 30 ml of the sulphuric acid solution 2. Rinse the burette with 5 mL of base and discard the base. 3. Using a funnel as an aid, fill the burette with base. 4. Using the pipette, transfer 10 mL of the acid into the Erlenmeyer flask. 5. Add 2-3 drops of phenolphthalein. 6. Titrate the acid with the KOH. (The endpoint colour is a permanent light pink) 7. Repeat steps 5-7 until you have at least two titrations that are within 20.2 mL of each other. 8. Return any uncontaminated base to the flask on the front desk 9. When done, rinse the pipette and burette with distilled water 10. Hang the burette upside down in the stand with the valve open 11. Clean up as instructed by your teacher. Observations Trial 1 Initial volume of KOH (ML) 0.00 48.5 Final volume of KOH (mL) 48.5 972 Volume of KOH used (ml) Bossono cone 3 972 145.5 Average volume of NaOH (mL) used Calculations Given equation: H.SO (aq) KOH(aq) - K SO(aq) - HOM) Calculate the concentration of the sulphuric acid solution Your Report Must Include the following, Calculation Conclusio
