Final answer:
The density of ethyl acetate is affected by temperature and pressure, with density generally decreasing with increased temperature and increasing with higher pressure. Understanding the density of ethyl acetate is crucial for precise measurements in chemical syntheses and other applications.
Step-by-step explanation:
Investigating Temperature and Pressure Effects on Ethyl Acetate Density
When discussing the influence of temperature and pressure on the density of ethyl acetate, we need to know that density is defined as mass per unit volume.
Generally, gases are less dense than liquids or solids at room temperature. As the temperature increases, the density of a material typically decreases because the material expands and its volume increases. Similarly, an increase in pressure can lead to a higher density if the material is compressible because it reduces the volume.
Let's take an example. A liquid sample with a mass of 22.8 grams and a volume of 14.7 mL has a density of 22.8 grams / 14.7 mL = 1.55 g/mL. If we have a material with a density of 2.7 grams/mL taking up 35.6 mL, the mass of the material is 2.7 grams/mL * 35.6 mL = 96.12 grams. A high-density material at 19.3 g/mL could be something dense like gold.
In the case of ethyl acetate, its density changes accordingly with temperature and pressure. With a density of 0.9003 g/cm3, we can determine the mass of ethyl acetate produced in a reaction using its mass-to-volume ratio.
Practical applications that utilize the relationship between temperature, pressure, and density are abundant, such as in chemical syntheses where precise measurements of reactants and products are crucial.
For an ether like diethyl ether, a low boiling point means that it readily vaporizes; this characteristic is influenced by its intermolecular forces.
At high altitudes, where atmospheric pressure is lower, water boils at a lower temperature, which explains why it takes longer to cook an egg at high altitudes like Ft. Davis, Texas, compared to sea level locations like Boston.
