Click to see additional instructions The literature value for the pkc of bromocresol green is 4.70 at 25 degrees Celsius. A student experimentally determined the pkc value of bromocresol green as 4.67. What is the % relative error for this student's result? Report answer to correct # of sig figs (incorrect sig fig use means the answer is marked completely wrong)! Insert answer here without units:
