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
What are two different ways to measure volume? length x width x height or put water in a graduated cylinder, and measure the volume of water. then place the object in the graduated cylinder and record the new volume of the water. subtract the old volume from the n...
I'd say the more precise, and therefore better, way is to measure the volume of ink in the container prior to the filling process, then again after the pen is considered completely filled (with however many steps or iterations of whichever filling procedure). Some ink could be trapped in ...
Measure out approximately 50 mL of cold water using the graduated cylinder. There's no need to be exact at this stage. Step 4 Measure the weight of your empty coffee-cup calorimeter to the nearest 0.01 grams (or as close as you can get). Now, add the 50 mL of cold water, replace ...
Fill a graduated cylinder with enough water so that the solid can be completely submerged later. Step 2 Measure the amount of water in the graduated cylinder. Step 3 Place the solid into the graduated cylinder. Step 4 Measure the amount of water in the graduated cylinder. ...
To prepare reagents, first bring all kit reagents to room temperature. To prepare your wash buffer, add 20 mL of wash buffer concentrate to 480 mL of deionized or distilled water in a graduated cylinder to yield 500 mL of wash buffer. Mix gently. ...
Re:How to experiment to measure a volume of gas « Reply #3 on: January 21, 2006, 10:36:23 PM » If you want a quantitative measure of the gas produced, take a graduated cylinder and fill it, then invert it in a tank of water. Run a tube from your reaction vessel into the...
The error in the experiment is that the graduated cylinder that is used to measure volume is not dried in-between uses. Step 3:Determine what measured value identified in step one is impacted by the observed error. If the graduated cylinder is not dried between uses, we would expect it ...
Pour wash into Air Still, close lid, turn on Air Still and wait for distillate to start dripping from it. Collect alcohol with either stainless steel or glass collection container. Using the Hydrometer and graduated cylinder measure you %abv (alcohol by volume) of the moonshine. You should be...
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...
