figure rules in each calculation. 1. Part I: Density of Unknown Liquid 1. Calculate the mass of the liquid for each trial. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) Trial 1 36 - 25.5 = 10.5 Trial 2 36.5 - 25.5 = 11 Trial 3 36.9 - 25.5 = 11.4 2. Calculate the density of the unknown liquid for each trial. (Divide the mass of the liquid calculated above by the volume of the liquid.) Trial 1: 10.5 / 8.7 = 1.21 Trial 2: 11

hydrometer is an instrument to measure the relative density of liquids. It consists of a tube with a bulb at one end. Lead shots are placed in the bulb to weigh it down and enable the hydrometer to float vertically in the liquid. In a liquid of lesser density‚ a greater volume of liquid must be displaced for the buoyant force to equal to the weight of the hydrometer so it sinks lower. Hydrometer floats higher in a liquid of higher density. Density is measured in the unit of g cm-3. 4. SHIP
Premium Density
ABSTRACT The densities of several liquid and solid samples were determined as an exercise in measurement. Density‚ being an inherent and intensive property of a substance‚ was also used to determine the identity of an unknown liquid sample. Proper procedures on measurement were observed in order to determine the mass‚ volume‚ and density of the samples. Four liquid samples were used namely water‚ isopropyl alcohol‚ coconut oil‚ and an unknown liquid sample. The experimental density values were measured

Information of Michael King’s lab sheet can state two conclusions. The first conclusion that can be stated from information of the lab is water seeped through some of the oil. The density of the water was 1.1 g/mL and the soap was 1.446 g/mL‚ the soap was clearly denser than water. For proof that the water seeped through the soap Michael King’s observation sheet of water stated: “The water is leaking down into the soap‚ but still sits on top of the dish soap.” Later through his observations it elaborates

Describe some exceptions to the statement if there are any. In general‚ solids are denser than liquids‚ and liquids are denser than gases. 5. Use the particle theory to explain why changing the temperature of a fluid can also change its density. 6. The density of a fluid usually decreases as the temperature
