since the density is the mass of a certain volume, density is found by dividing mass by volume. here, the mass is proportional to the volume, so the mass of the metal divided by the volume should be constant. this means that the mass of any volume of the metal can be found by multiplying the volume by the density .
How do you find the mass?
Mass is always constant for a body. One way to calculate mass: Mass = volume × density . Weight is the measure of the gravitational force acting on a mass. The SI unit of mass is “kilogram”.
What is the mass of a piece of metal?
The mass of a piece of metal is 19.5061 grams . When the piece of metal was dropped into a graduated cylinder
What is the mass of the unknown metal?
Explanation: If one mole of an unknown metal has a mass of 63.55 g , then its molar mass is 63.55 g/mol . Molar mass is numerically equal to atomic weight. You can look at the atomic weight of the metals on the periodic table.
How do you find the mass of a metal in water?
Fill a beaker half-way and record the volume of water. Insert the metal into the water and record the new volume of water. Subtract the initial volume of water from the final volume to determine the volume of the metal. Divide the mass by the volume to calculate the density of the metal.
How do you find the mass with density and volume?
- Look up the density of the material the object is made of in kg/m3.
- Measure the volume of the object in m3.
- Multiply the density by the volume.
- You will then have the mass of the object in kg.
How can you identify an unknown metal?
You can identify an unknown substance by measuring its density and comparing your result to a list of known densities . Density = mass/volume. Assume that you have to identify an unknown metal. You can determine the mass of the metal on a scale.
How can you determine the atomic mass of an unknown element?
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons . Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
How can I calculate weight?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s 2 on Earth. The formula for calculating weight is F = m × 9.8 m/s 2 , where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is metal density?
Density is defined as a object’s mass per volume .
What is the mass of water?
This is stated: the molar mass of water is 18.02 g/mol .
How do I find mass from volume?
Volume equals mass divided by density ; and. Mass equals density times volume.
How do you convert volume to mass?
Volume equals mass divided by density ; and. Mass equals density times volume.
What is the formula of volume?
| Table 3. Volume Formulas | Shape Formula Variables | Cube V=s3 s is the length of the side. | Right Rectangular Prism V=LWH L is the length, W is the width and H is the height. | Prism or Cylinder V=Ah A is the area of the base, h is the height. |

Can you use specific heat to identify an unknown metal?
Both specific heat and density are physical properties that can be used to identify an unknown element.
