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.
Are non metal invisible?
Yes: wave a metal detector over the sample. If nothing happens, it's a non metal.
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.
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 volume of the metal cylinder is 21.4mL - 15mL = 6.4mL. This is the water displacement method for determining the volume of an irregular solid.
What metal ion would you predict to be contained in sample of unknown 1?
Strontium and copper nitrate
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.
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).
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 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 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.
Which is more dense, a 200 g sample of zinc metal or a 500 g sample of zinc metal?
500g
What is more dense a 200g sample zinc metal or 500g?
Which is more dense a 200.g of zinc metal or a 500g sample of zine metal?
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.
If a 100-gram sample of platinum metal has a volume of 4.67 milligrams what is the density of platinum in gcm3?
the answer is 21.41,its a 99.7% pt. since the density of pt is 21.46 g/cm3.
How does the density of a metal in the crushed can compare with density of the metal before the can was crushed?
The density of the metal will remain the same. However because the volume of the object has been reduced the overall density will increase
A metal sample weights 56.8grams How many ounces does this sample weight?
2.00 oz
