1. Find the mass (in grams) of the metal cylinder using the triple beam balance. Attach one end of a thin thread to the bottom of the balance and the other end to the hook in the metal cylinder. Find the mass of the cylinder as it hangs from the bottom of the scale and is completely submerged in water. The cylinder should not touch the bottom or sides of the can. Record these masses 2. Empty the can of water, dry it thoroughly, and refill it with alcohol. Find the mass of the metal cylinder when submerged in the alcohol. Record this mass. 3. Empty the can of alcohol and refill it with water. Find the mass of the wooden cylinder in air. Attach the wooden cylinder to the thread under the balance. Hook the lead sinker to the thread below the cylinder. Measure the mass of the two solids when the sinker is under the water and the wooden cylinder is above the water. Measure the mass of the solids when both are completely submerged in the water. Make sure they do not touch the bottom or the sides of the can. Record these masses. 4. Measure the specific gravity of the alcohol using the hydrometer set up at the front of the lab. Record the specific gravity. DATA: Mass of metal cylinder in air Specific gravity of alcohol Apparent mass of metal cylinder in water Percent error Apparent mass of metal cylinder in alcohol Mass of wooden cylinder in air Specific gravity of metal cylinder Apparent mass of cylinder in air and sinker in water Percent error Apparent mass of cylinder and sinker both in water Specific gravity of alcohol by using Specific gravity of wooden cylinder CALCULATIONS: 1. Calculate the specific gravity of the metal cylinder and the percent error between it and the theoretical value. 2. Calculate the specific gravity of the alcohol and the percent error between it and the theoretical value. 3. Calculate the specific gravity of the wooden cylinder
