a. What is the mass of water displaced?
b. What is the volume of water displaced?
c. What is the density of rock?
A rock with a mass of 489 g in air is found to have an apparent mass of 308 g when submerged in water. (a) What mass (in g) of water is displaced? g (b) What is the volume (in cm3) of the rock? cm3 (c) What is its average density (in g/cm3)? g/cm3 Is this consistent with the value for granite? Yes O O No
A rock with a mass of 537 g is added to 50.1 mL of water. The water level rises to a volume of 77.1 mL. What is the density of the rock?
A rock with a mass of 714 g in air is found to have an apparent mass of 352 g when submerged in alcohol (density is 0.750 g/cm3). What mass of the alcohol is displaced?
A rock with a mass of 613 g in air is found to have an apparent massof 329 g when submerged in alcohol (density is 0.750 g/cm3). What mass of the alcohol is displaced?
1. A 20 kg block displaces 5 L of water. Determine its weight in air and water. 2. A ship weighs 20,000 tons and can displace a maximum of 150,000 tons of water. a Determine its maximum cargo weight. b If the cargo is wood with a density of 0.02 tons/ft determine the volume of wood the ship can carry . A rock has a density of 6.0 g/cm and a mass of 72g. a What is the volume of...
3. Suppose you have a rock with a mass of 305 g. When attached to a spring scale and lowered completely into water the spring scale reads Fe 2.10 N. Note that this reading is significantly lower than the rock's weight Fo Mg (3 N), because of the buoyant force helping to support it. From this information, calculate the following: (a) Fe: the magnitude of the buoyant force exerted on the rock. Use N2L in conjunction with the FBD shown...
A 7.9 g rock sample is added to a graduated cylinder filled with water, causing the level to increase from 10.6 mL to 16.8 mL. What is the density of the rock sample? Select the correct answer below: A) 1.6 g/mL B) 1.3 g/mL C) 2.1 g/mL D) 2.5 g/mL
Data: Mass of flask filled with air - 150.9425 g Mass of flask filled with CO2 Trial 1 - 150.9775 g Mass of flask filled with CO2 Trial 2 - 150.9805 g Average mass flask filled with CO2 - 150.979 g Temperature of CO2 - 296.15 K Barometer reading - 1.0 atm Density of water at room temp - 0.9978g/mL Density of dry air in flask at room temp - 1.201g/L Calculations: Mass of water in flask - 392.85 mL...
Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 46.0 g46.0 g and its apparent mass when submerged is 3.60 g3.60 g (the bone is watertight). What mass of water is displaced? mass of water displaced: kgkg What is the volume of the bone?...
Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g(the bone is watertight). What mass of water is displaced? mass of water displaced: kg What is the volume of the bone? volume of the...
