May 08, 2012 · Using a 250-mL graduated cylinder, add to the ?ask while continuously stirring its contents, 50/NKOH6 1 mL of 0.2 M alcoholic KOH solution. (NKOH being the exact molarity of the KOH solution found by standardization). Dilute to the 1000-mL mark with anhydrous isopropyl alcohol and mix thoroughly. Use within 2 weeks. 7.5 Chloroform, reagent grade.

Answer. In the 25-mL graduated cylinder, first subtract 25 mL - 20 mL = 5 mL. Next, count that ten intervals are between the labeled graduations. Therefore, the scale increment is 5 mL/10 graduations = 0.5 mL/graduation. Use the labeled graduations and the scale increment to find the certain digits in the measurement.

    1. Answer (1 of 4): When you measure to the nearest "mark" or "spot" where the measurement value is… you're supposed to be able to tell which mark it's closer to when you have something that lines up in the middle of two marks… so if you're measuring to the nearest .1 of a ml… and the stufff falls i...

    3. Dry gas meter, sufficiently accurate to measure the sample volume to within 2 percent, and calibrated over the range of flow rates and conditions actually encountered during sampling. 6.2.8 Rate Meter. Rotameter, or equivalent, to measure the flow range from 0 to 3 liters/min (0 to 0.11 cfm). 6.2.9 Graduated Cylinder. 25-ml. 6.2.10 Barometer.
    4. The eluate (specimen filtrate) was collected in 7 fractions with increasing volume (associated with specimen dry mass), until the obtained L/S (liquid to solid) ratio = 10 dm 3 /kg d.m. The reaction and specific conductivity were determined in eluates obtained this way, and after they were preserved with nitric acid (V), the heavy metal content ...
    5. Add 1 mL for each line below it and above the next numbered line. If the top of the plunger rests three lines down from the line marked "5," then there are 8 mL of liquid in the syringe. If it rests two lines down from the line marked "15," then there are 17 mL of liquid in the syringe.
    6. The vertical tube is graduated from 0 to 5 mL with each gradation representing an increment of 0.5 mL (It is therefore possible to estimate to 0.25 mL). The total height of the column of water applied to the surface, measured from the center point of the flat, circular brim to the topmost gradation, is 12 cm.
    7. At a site there is 15 thick layer of sand with water table at 10' depth. Top 10' of sand was dry with e = 0.6, Gs = 2.65. Below the WT the sand had e = 0.48. Underneath the second sand layer was 15' thick clay deposit, with w = 33 %, Gs = 2.75. Draw total stress, pore water pressure and, effective stress diagrams for the entire depth. Gradation ...
    8. For each of the volume reading values in Table 1, subtract the volume reading from the previous row and record the result in the column marked "Volume by Difference". This calculation allows you to obtain the volume associated with each piece of metal you added to the graduated cylinder. (See the example data table on the next page.)
    III. Volume of a Liquid 1. Examine the 25 mL graduated cylinder provided to you and determine the smallest increment marked. Record this increment in your data table. 2. Examine the 1000 mL graduated cylinder at its designated station in the lab and determine the smallest increment marked. Record this increment in your data table.
The 100mL has an increment of 5mL so it's harder to see the exact measurement. The 10mL has the smallest increment of 0.1mL which allows a scientist to measure better. The uncertainty of the 100mL graduated cylinder was ±5mL while the 10mL graduated cylinder has an uncertainty of ±0.1mL. 3. Based on the results, the balance was more accurate.

Results for dispenser #2 represent improved accuracy (each volume is less than 3 mL away from 296 mL) but worse precision (volumes vary by more than 4 mL). Finally, she can report that dispenser #3 is working well, dispensing cough syrup both accurately (all volumes within 0.1 mL of the target volume) and precisely (volumes differing from each ...

A sample of 20 g of each powder is poured into a 100‐ml graduated cylinder containing 50 ml of distilled water at 25°C. The test tube is capped, and 10 successive turns are made so as to hydrate all the particles. 50ml of water is added to lower the particles remained stuck along the wall.
