It is displacing 2.79 lb of water, so its volume is
(2.79 lb)/(62.4 lb/ft^3) = 0.0447 ft^3.
Its weight (in air) is 8.05 lb,
so its weight-density is
8.05 lb/(0.0447 ft^3) = 180.1 lb/ft^3
An irregularly shaped piece of a solid material weighs 8.05 lb in air and 5.26 lb...
An irregularly shaped piece of aluminum has a mass of 35.65 g. What volume (in mL) of water should displace if it is solid all the way through? Aluminum has a density of 2.7 g/cm3
If an irregularly shaped object displaces 3.0 gallons of water, and weighs 14.25 pounds, calculate the density of the object in terms of grams and cubic centimeters. Show steps.
A 2-liter graduated cylinder initially contains 500ml of water. An irregularly shaped object having a mass of 105gm is submerged into the water. The final volume of the water in the cylinder is 1025ml. Determine the density of the object.
2. A piece of jewelry was tested by method A (Density of Irregularly Shaped Solids by Water Displacement) to determine if it was pure silver or a silver-plated resin. The mass of the jewelry was 1.52 g. A chemist measured the volume displaced by the item, then repeated the experiment. She obtained two different values, 0.16 mL and 0.14 mL. Calculate the density of this item using each volume amount. How do the experimentally obtained density values compare to that...
Problem 1. A 15 kg ball weighs 147 N in air and weighs 118 N when submerged in water. The buoyant force of the water on the ball is: Problem 2. 3.5 kg of a solid copper (density: 8,920 kg/m3 ) submerged in water. What is the buoyant force on the solid coppor block in the water?
Someone tries to sell you a solid but irregularly shaped lump of gold, but you are suspicious because you think that it feels too light. Because it is irregularly shaped, you cannot easily calculate its volume from measurable linear dimensions. So this is what you do. You weigh the lump of gold on a pan balance (weight scale) that reads in kg up to a maximum of 80 kg. The scale reading is 25.95 kg with the gold lump resting...
An object has a weight of 8N in air. However, it apparently weighs only 4N when it is completely submerged in water. What is the density of the object?
An object weighs 25.0 N in the air and 20.0 N when completely submerged in water. What is the density of the object? (The density of water is 1000 .) o o ooo o sooo o o soooo *
Problem 6 An object has a weight of 8 N in air. However, it apparently weighs only 4 N when it is completely submerged in water. What is the density of the object?
If a man weighs 220 lb with a body fat percentage of 28%: (a) What is the density of this person's body in kg/m^3? (b) What is the volume of the person's body? (c) Find the apparent weight of this person when completely submerged in water. Assume fat has a density of 900 kg/m^3 and fat-free body mass has a density of 1100 kg/m^3.
