How can you find displacement of a metal in 50 mL of water when given the mass?
Place the piece of metal in 50mL of water and subtract the 50mL from the new volume of water. The difference will be the volume of the metal in mL and cm3. Then find the density by dividing the mass by the volume of the metal. The water must completely cover the metal in order for the displacement method of determining the volume to work.
What is the volume of a metal cylinder weighing 18.03 grams if you put it in 15mL of water and it rises to 21.4 mL?
The increase in volume of the water when the cylinder is added is equal to the volume of the cylinder. So, the volume of the cylinder is 21.4 mL - 15 mL = 6.4 mL. Since the metal cylinder is immersed in water, the volume of the metal cylinder is 6.4 mL.
What mass does metal block displace?
The metal block will displace a volume of water equal to its own volume. By measuring the volume of water displaced, you can then determine the mass of the metal block - as long as you know the density of water (1 gram per cubic centimeter).
How many number of moles are in al metal cube?
This depends on: the volume of the cube, the density of the metal, the atomic weight of the metal.
How do scientists determine metal composition?
Scientists determine metal composition using techniques such as spectroscopy, x-ray fluorescence, and mass spectrometry. These methods analyze the elemental makeup of a sample by measuring the emission or absorption of energy when it interacts with the metal atoms. By comparing these signals to known standards, scientists can identify and quantify the metals present in a sample.
What metal has a mass of 35.4 and a volume of 3.11?
A sample of an unknown metal has a mass of 35.4g and a volume of 3.11cm^3. The metal is Lead.
What is the density of a metal sample of a 37.51-g sample placed into a graduated cylinder increases the liquid level from 50.0 ml to 57.5 ml?
The volume of the metal sample can be calculated as the difference in the liquid level before and after adding the metal. In this case, the volume displaced by the metal is 7.5 ml. The density of the metal sample is then calculated by dividing the mass of the sample (37.51 g) by the volume displaced (7.5 ml), resulting in a density of 5.0 g/ml.
Will air bubbles affect the volume when measuring the volume of a metal.?
Yes, air bubbles can affect the accuracy of volume measurements for a metal. The presence of air bubbles can displace the metal, leading to an inaccurate volume measurement. It is important to remove any air bubbles before measuring the volume of a metal sample.
If A sample of metal has a mass of 94.5 grams and a volume 7 cubic centimeters what is the density?
Based on the formula Desnity= Mass/Volume. The answer would be 13.5 g/cm3
How does density change as the universe expands?
The density of what? Any metal, liquid, etc. will have the same density since density depends on mass and volume of the sample (not volume of the universe).
What is more dense a 200g sample zinc metal or 500g?
The 500g sample of zinc metal is more dense because density is a property of a material and does not depend on the amount of the substance. Density is defined as mass divided by volume, so for the same material, the one with higher mass will be more dense.
How could you identify a pure metal if you a balance a graduated cylinder and a table of densities for metals?
First, measure the mass of the metal using a balance. Next, measure the volume of the metal by filling a graduated cylinder with water and then dropping the metal into the cylinder. Finally, calculate the density of the metal using the formula density = mass/volume. Compare the calculated density to the table of densities for metals to identify the pure metal.
Was the water in a cylinder before the sample was added?
after 5.63 gm sample of wood metal was added in a 10ml graduated cylinder the new water level is 8.7ml "http://wiki.answers.com/Q/Was_the_water_in_a_cylinder_before_the_sample_was_added" after 5.63 gm sample of wood metal was added in a 10ml graduated cylinder the new water level is 8.7ml "http://wiki.answers.com/Q/Was_the_water_in_a_cylinder_before_the_sample_was_added"
How does the density of the metal in a crushed can compared with the metals density before the can was crushed?
The density of the metal in a crushed can remains the same as the density of the metal before the can was crushed. While the volume of the can decreases when it is crushed, the mass of the metal remains constant. Therefore, the density, which is mass divided by volume, remains unchanged.
Which is more dense, a 200 g sample of zinc metal or a 500 g sample of zinc metal?
Both samples have the same density because they are made of the same material, zinc metal. Density is a property of the material and is independent of the quantity of the material present. Density is determined by the mass and volume of the material, not the amount of the material.
How does a piece of metal in a graduated cylinder of water allows you to figure out the volume?
The reading on the graduated scale is taken before and after the metal is lowered into the cylinder . The second reading is subtracted from the first. This gives the volume of the metal in cubic centimetres.
If 400kg of a metal measures 20cm X 50cm X 80cm find the density of the metal?
The mass of the sample is 400 kg = 400,000 grams.The volume is (20 x 50 x 80) = 80,000 cm3The density is (mass / volume) = (400,000 / 80,000) = 5 gm/cm3
