EXPERIMENTAL PROCEDURES 4. Meering Length Mature Meiring In the estimated digitinesch measurement & Indie mumber of significant figures in each measurement your value with those of two other students. B. Measuring Volume cylinders, solid object, thread Volume of a liquid 1. Read the volume of each of the liquids in the display of graduated cylinders. Be as precise as you can Be sure to estimate between the smallest markings to obtain the estimated digit. Volume of a solid by displacement 2. Obtain a graduated cylinder that will fit the solid object. Place water in the graduated cylinder until it is about half full. Record the volume, in milliliters, of water. 3. Tie a piece of thread around the solid object. Slowly lower the solid object until it is completely submerged, Record the new volume of the water. 4. Calculate the volume, in milliliters, displaced by the solid. C. Measuring Mass Materials: Balance, objects to weigh (beaker, rubber stopper, evaporating dish), unknown mass Your instructor will show you how to use a laboratory balance. Be sure the reading is 0.00 when the balance pan is empty. 1. Separately place each object on the balance pan and record its mass. 2. Obtain the object of unknown mass and record its code number. Place it on the balance pan record its mass. 3. Obtain the mass of the object from your instructor and compare to your experimental value. 4. Determine the correct number of significant figures for each mass obtained. and GOGGLES REQUIRED! One themes on ametlik.
