Chemistry Lab Drawer Graduated Cylinder Graduated Cylinder

Graduated Cylinders Use these to accurately measure liquids in lab. Never use beakers to measure. Use these to accurately measure liquids in lab. Never use beakers to measure. The answer on the SOL to this question is always GRADUATED CYLINDER. The answer on the SOL to this question is always GRADUATED CYLINDER. Accurate to within ± 0.05 ml. (This is ½ of the smallest division line on the cylinder.) Scientists call this the “uncertainty” of the measurement. Accurate to within ± 0.05 ml. (This is ½ of the smallest division line on the cylinder.) Scientists call this the “uncertainty” of the measurement.

Volumes. We will work with liters (L) and milliliters (mL) in this class. We will work with liters (L) and milliliters (mL) in this class. You should know that 1000 mL = 1L. You should know that 1000 mL = 1L. Also know that cubic centimeters (cm 3 ) and milliliters (mL) are different names for the same amount. So, 1 mL = 1 cm 3. Also know that cubic centimeters (cm 3 ) and milliliters (mL) are different names for the same amount. So, 1 mL = 1 cm 3. 1 drop from a dropper is approximately 0.05 mL. So, 20 drops = 1 mL. 1 drop from a dropper is approximately 0.05 mL. So, 20 drops = 1 mL.
