ACTIVITY ACTIVITY 2 A Determining the Densities of Solutions 1. Weigh an empty 50-ml graduated cylinder. Record the mass in Data Table 2. 2. Add 5 mL of water (0% sucrose) to the 50-ml graduated cylinder. Use the pipet to add or remove small quantities of liquid so that the water is exactly at the 5-mL mark. 3. Record the Mass of Solution + Graduated Cylinder in Data Table 2. 4. Add more water until the cylinder contains 10 mL...

EXPERIMENT 1: ECOLOGICAL INTERACTIONS In this experiment, you will demonstrate how substances accumulate in trophic levels through biomagnification PROCEDURE 9 mL of water into the 10 ml graduated cylinder. The graduated cylinder represents a primary producer. □ 2. Add 1 mL f oil to the 10 ml graduated cylinder containing the water. Note that the...
Part A: The stockroom provided label on the graduated cylinder says that the empty weight is 31.08g. A chemist then places this cylinder on a balance and adds potassium hydroxide until the total weight of cylinder and chemical was 59.179g. She added water to the graduate cylinder and dissolved the potassium hydroxide completely, then she read the toa; volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 73.9mL. What molar concentration...
You need to determine the density of an object. You place it in a graduated cylinder that has 25 mL of water in it to start. The water level rises up to 29 mL after the object is added. If the mass of the object is 8 grams, calculate the density
You measure the volume of water in a graduated cylinder marked down to the tenth of a mL. It starts with a water level indicating 28 mL. You then drop an unknown object into the cylinder for a new level indication of 34.4 mL. You remove and dry the unknown object, measuring its mass to be 22.352 +/- 0.003g. a) Calculate the density of the unknown object in kg/m3 . (Density = mass/volume). Unit conversion factors are known exact quantities...
A sample of unknown liquid is weighed in a graduated cylinder and the mass is 130.6g. The empty graduated cylinder weighs 100.3 g. The volume of the liquid is 28.15 mL. What is the density of the liquid?
In the lab, a student fills a dry 50 mL graduated cylinder with 30.0 mL of water. The mass of the water in the graduated cylinder was 30.743 grams at 25°C. What is the true volume of the water measured in the graduated cylinder? The density of water at 25°C is 0.99707 g/mL.
An empty graduated cylinder weighs 56.90 g. A student puts 24.6 mL of an unknown liquid into the cylinder and the mass of the cylinder plus the liquid equals 98.47 g. What is the density of the unknown liquid (in g/mL)?
10. a) Report the volume (in mL) of liquid inside the graduated cylinder by reading the bottom of the meniscus (curved surface). 36.5 mL . b) What is the mass (in grams) of the liquid (d = 21.7 dg/ce) inside 881 the 50 mL graduated cylinder? de 88.188 g A ?g 50 mL graduated cylinder c) If all of the liquid inside the graduated cylinder was poured into the glass cup, what will the combined mass (in g) of both...
