Question
what is the value,in mL, of each graduation mark or increment on each beaker?
What is the volume reading, in mL, of each beaker?
DRY Beakers are flat-bottom cylinders with pour hey common in a variety of sizes and are used for measuring rough volumes of A typical beaker is accurate within about In other words, a 250 25 A mL beaker will be accurate to within about t100 Beakers are used 250 mL mL liquids. mL. for mixing and transferring Illustrated below are m for beakers. Only the centre part of the beaker is illustrated. Three sizes are given: 100 mL, 250 mL, and 500 mL. Notice the markings on the beakers. Most beakers. are marked with a "t5%", meaning that each reading can vary by 5-10%. For instance, abeaker Contained 100 mL of water, the actual value could range 5% either way ffrom g5 ml to 105 ml). Beakers are used for only approximate measurements. Never use a beaker for measuring when very accurate data is being sought. Determine the graduation markings or increments on each beaker. Record these values in the Data Table. Determine the reading marked by a question mark and an arrow Which is more accurate? A beaker or a graduated cylinder 500 mL --10% 250 mLt10% 100 mL +10% 500 mL 250 mL 100 mL D D 0 mL. 0 mL an unl hnakar using a 100 mL graduated VETExplanation / Answer
for a graduated scale of figure one, each reading corresponds to 16.66 mL.(divide the tota volume /no of scale graduations )
The arrow mark corresponds to 66.67 mL, and the volume reading is also the same 66.67 mL.
---------------------------------------------------------------------------------------------------
for a graduated scale of figure one, each reading corresponds to 41.66 mL.(250/6)
The arrow mark corresponds to 62.49 mL, and the volume reading is also the same 62. 49 mL.
---------------------------------------------------------------------------------------------------
or a graduated scale of figure one, each reading corresponds to 50 mL.(500/10)
The arrow mark corresponds to 275mL, and the volume reading is also the same 275 mL.
