A wet metal sample can have water molecules attached to its surface, which can affect its mass and volume measurements. Removing water ensures accurate data and prevents errors in calculations.

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?

one method is to digest the metal using an acid and then use atomic absorption spectroscopy to determine which metal and how much of that metal is present in the solution. You can then work backwards to determine how much of a particular metal was in your sample (you need to know how much metal was used to make the solution).

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?

Density is defined as mass/volume. The mass of the sample is 37.51 g. The volume of the sample is that volume of water that is displaced, i.e. 57.5 - 50.0 ml = 7.5 ml. Density = 37.51 g/7.5 ml = 5.0 g/ml. This is reported to 2 sig figs based on the subtracted value of 5.0


Will air bubbles affect the volume when measuring the volume of a metal.?

Air bubbles would make the volume you read in the measuring cylinder increase from the actual volume of theliquid. so when you add in the metal, there would be an increase in the volume of the metal than it really is. the mass of the metal cannot be affected by air bubble because this is the amount of matter in the metal. This increase in volume causes the density of the metal to reduce from its original value. since mass is constant, density is inversely proportional to volume. As volume increases, density decreases.hope that was helpful.


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?

Mass divided by volume, same as it is for anything else. The density of metals ranges from around 500 kg/cubic meter up to around 22000 kg/cubic meter, so if you were hoping for a value ... somewhere in that range, which is a pretty wide range, depending on which specific metal you're talking about.

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.


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


Will the volume of metal decrease if it is heated?

No, the volume of a metal increases as it is heated. It expands.
