since the volume of an object can be known from other measurements. In order to find the volume of a rectangular box, for example, one only needs to know the length, width, and depth of the box. Then the volume can be calculated from the formula, V = l · ...
When we need to measure the volume of a liquid accurately, we use the ___. A. 山原质手书但文则下资自组效温路方山原质手书但文则下资自组效温路方burette山原质手书但文则下资自组效温路方山原质手书但文则下资自组效温路方 B. 个方构准议上较期时调林适铁还适看运二成个方构准议上较期...
burette readings were incorrectly subtracted to obtain any of the accurate titre values.All burette readings, excluding initial 0, (resulting in titre values used in calculation of mean) are integers.Note: the candidate's mean will sometimes be marked as correct even if it is different from the...
What is the size of the nucleus? What is space? What is a peso? Find the concentration of NaOH and HCl using the information provided: Volume of NaOH used to be titrated in conical flask = 25 cm^3 Volume of HCl from burette used to titrate the NaOH = 38.2 cm^3 ...
aOne way of doing this is to connect the burner tube with a short length of tubing(about 7mm internal diameter)to a soap bubble flowmenter,such that the upward passage of a soap film meniscus in a glass tube of calibrated volume(e.g.a burette)over a known period of time gives an abso...
Which instrument(s) has (have) the greatest precision for measuring volume: 10 mL graduated cylinder, 50 mL graduated cylinder, 50 mL burette, 10 mL graduated transfer pipette, and 10 mL volumetric pi Which measuring device could you use to transfer 50.0 mL of liquid?
A. burette B. pipette C. graduated cylinder D. test tube 相关知识点: 试题来源: 解析 C。graduated cylinder 是量筒,用于准确测量液体体积;burette 用于滴定分析;pipette 用于精确量取少量液体;test tube 是试管,不用于测量体积。准确测量液体体积用量筒,故选 C。反馈...
All Class A PMP volumetric flasks are optionally available in transparent or UV-absorbing variations for light-sensitive substances. Calibration Type "Ex": The delivered quantity of liquid corresponds to the volume printed on the instrument (pipettes and burettes). Type "In": The contained quantit...
What is a burette used for? A. Measuring mass B. Measuring volume of liquid accurately C. Heating solids D. Stirring liquids 相关知识点: 试题来源: 解析 B。选项 A“Measuring mass”是测量质量,滴定管不能测量质量。选项 B“Measuring volume of liquid accurately”是准确测量液体体积,这是滴定管的...
