To find the volume of an irregular shape, you need to use the water displacement method. If the object can fit into a graduated cylinder, fill the cylinder with enough water to adequately cover the object, but
When using a graduated cylinder to measure the volume of a liquid, how should we read the scale? A. Read at the top of the meniscus B. Read at the bottom of the meniscus C. Read randomly on the meniscus D. Read at the side of the graduated cylinder ...
Suppose a graduated cylinder wasn't correctly calibrated, how would this effect the results of a measurement? In making a specific galvanic cell, explain how one determines which electrodes and solutions to use in the cell. Explain the effect on the c...
The bulk density (ρb) of powders was performed in duplicate (n =2) using a graduated cylinder (10 cm3) and laboratory scale. This was calculated as follows: ρb=mVbρb=mVb (1) m—mass of the powder, Vb—volume of the powder ...
It's important that your lab equipment is set up and calibrated correctly.Calibrationinvolves making sure the scale isn't off by a certain amount, that zero really means zero. For example, we use scales and balances to measure the mass of an object in kilograms, grams, or pounds. But it...

9.To prepare a buffer, use 25 mL graduated cylinder to add 10 mL of 0.10 M HC2H3O2 and 10.0 mL of 0.10 M NaC2H3O2 to a 100 mL beaker. 10.Measure the pH of the buffer solution and record. 11.Add 1 drop of 0.10 M HCl, stir, measure and record the pH. ...
Which is more precise for measuring volumes of liquids, the volumetric pipet or the graduated cylinder? Why? Could you have determined which device is more precise by making a single measurement? Why or why not? What are qualitative data measurements? A. ...
When a metal has a low melting point you can, of course, just melt it and pour it into a graduated cylinder to measure its volume. But gallium, if there was any of it in this alloy, tends to "wet" a wide variety of other substances. So, presuming there was gallium or something th...
lead beads, are placed into a wider bottom part, above which a narrow graduated stem is located. The water to be tested is filled into a gradu- ated cylinder, into which the hydrometer is then gently lowered until it floats freely, without moving. The den- sity is then read off from ...
