Answer the following questions in complete sentences. 1) A student accurately determines the mass of a sample of a metal and then attempts to determine the volume of the metal sample from the displacement of a liquid. Air bubbles cling to the metal sample submerged in the liquid but the student does not notice them and does not eliminate them. How will the student’s experimental density be affected? Be as speciﬁc as possible. (For example, will it be higher, lower or the same? WHY?) {a U W ﬂu: (”JP/Millie] («/(ll be W TA, 6494.529 ulll Mei/(e Fl Gift/ear as f? 44% Halal l5 ’l‘s/Crog _ H‘UJ W “More faeh “Mn .4 remit] {5.

Instead of rinsing the pipet used to deliver the solution with some of the solution the student rinses only with deionized water. How will the student’s experimental density be affected?

For good precision, density measurements should be within 0.005 g/ ml. Use complete sentences and make certain to clearly communicate an understanding of the term precision. Identify possible reasons Jfor any lack of precision. {L ’l/LU’AI— d9Wfa-l-c7 Celwl‘vddla (am/M1 LL/l’lL'V-t O‘COSé/hﬁ Orc- Qqcl,‘ all/LIV. ([61?)
