An ore sample weighs 18.5 NN in air. When the sample is suspended by a light cord and totally immersed in water, the tension in the cord is 10.2 N. 1) Find the total volume of the sample. Express your answer in meters cubed. 2) Find the density of the sample. Express your answer in kilograms per meter cubed.

The density of a composite is 1.7 g/cm3. The density of an unknown fluid is 2.2 g/cm3. An object made of the composite will _____ in the unknown fluid.

A scale is used to measure the weight of an object and it is 5.37 N. When the object is fully immersed in water, the scale reads only 3.43 N. What is the density of the object?

Question 1 a) A container of volume 2000 cm3 is completely filled by carefully pouring 1.7 kg of powder into it. The powder has a Carr’s Index of 25% and particle density of 1.40 kgm3. What is the bulk density of the powder?   B)Calculate the bulk density of the powder in the container in part a) if it is tapped repeatedly.   C) Calculate the voidage of the powder before and after tapping

(1) a. Gold is sold by the troy ounce (31.103 g). What is the volume (in cm3) of 2 troy ounces of pure gold? cm3 b. Mercury is commonly supplied in flasks containing 34.5 kg (about 76 Ib). What is the volume in liters of this much mercury? C. A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density (in g/cm?) of a 200 g rock that displaces 81.0 cm³ of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on Archimedes' principle.) g/cm3

b. When a silver necklace is submerged in 30.74 mL of water, the water level rises to 22.80 mL due to the volume of the necklace. What is the mass of the necklace? 7720ML
