You are given a beaker of an unknown fluid, a beaker of water, and an irregular object of unknown density. The irregular object displaces 75% of its volume when floating in water, but 95% when it floats in the unknown liquid. a) What is the (average) density of the irregular object? b) What is the density of the unknown liquid?
A student needs to determine the density of an irregularly shaped object. This student prepares a solution mixture where the object is suspended. The collected data is shown in the table below. Liquid g Density mL Volume (mL) Chloroform 1.465 5.41 Ethanol 0.789 3.13 Determine the density of the object. Object's density mL
A student needs to determine the density of an irregularly shaped object. This student prepares a solution mixture where the object is suspended. The collected data is shown in the table below. Liquid g Density mL Volume (mL) Chloroform 1.465 7.81 Ethanol 0.789 2.53 Determine the density of the object. Object's density = 1.300 mL
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
Jordan obtains a silver metallic unknown. Jordan measure the mass of the metal to be 62.307 g. When the metal is placed in a graduated cylinder that contains 22.3 mL of water, the new volume is measured to be 29.1 mL. a) calculate the change in volume of water in the graduated cylinder. b) calculate the density of the metal. c) Jordan's teacher provides a list of possible unknowns. Determine the identity of the unknown. METAL DENSITY (g/mL) lead 11.35...
Can you use Archimedes' principle to find the density of an object that floats? a. Yes, attach a weight to the object and find the difference in buoyant forces. b. No, the object must be able to sink. c. Yes, a floating object will still displace fluid equivalent to the buoyant force.
1)The density of the unknown liquid with the volume of 13.3 mL and a mass of 8.86 g is _______________ g/mL . 2) Describe how you can use the graduated cylinder to determine the volume of a small, irregularly-shaped metal. 3) What safety precaution should you take when adding the irregularly-shaped metal into the glass graduated cylinder?
Describe how torque and equilibrium determine the mass of an unknown object.
2. A student needs to determine the density of two metal objects. The first object is a cube and the second object is a rectangular bar. The student uses calipers to measure the length of the objects. a. What is the density (in grams per milliliter) of the metal cube if it has a mass of 84.55 g and an edge length of 2.16 cm? g mL b. What is the density (in grams per milliliter) of the rectangular bar...
How would you determine the concentration of an unknown NiCl2 solution, if you have enough NiCl2 as a powder, a Spectrovis Plus and all the necessary equipment? (Absorption maxima is observed at lamda = 610 nm)
