How many significant figures can you report for your determination of R? Choose... (5pts) Which measurement most limits your determination of the correct value for R? Normal . BI U X2 X === Ex i | xi TEK (5pts) 2. If you don't add all of the HCl to the test tube because you see all of the Mg is used up but you still follow the directions in this lab report to calculate your volume of H2 produced how will it affect your value of R? Choose... (5pts) Explain your answer in detail. Normal BI U X X = TX
