What is the density of a sample that has mass of 77.0 g and a volume of 36 mL?
The density of the sample is about 2.14 g/mL
What properties could be used to help determine whether the sample is rreally zinc?
Melting point of the sample & Density of the sample
What is the mineral property defied by Density of the mineral sample divided by the density of water?
Specific gravity.
How are density and buoyancy are alike?
If a object has buoyancy it floats. A object also needs to have a density less dense than the object you want it to float on. Example: if you want a inner tube to float and jewelry to sink you make them out of different materials.
What is the density of copper if the volume of a sample is 30cm cubed and the mass is 267g?
The copper's density is 8.9 g/cm3
What is the density of a 26.5mL sample of an unknown substance that has a mass of 43.54g?
density = mass/volume = 43.54g / 26.5ml ≈ 1.643 g/ml
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
In determining the density of an unknown solid it was immersed in water if a portion of the sample sticks out the water how will this effect the calculation of the density?
this will cause the density to be lower than it actually is because it does not displace the full amount of water it should
What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
Kelly has a sample of an unknown substance. Which properties of the substance will be the same no matter how large or small her sample is?
All intrinsic properties will be the same regardless of sample size. Some examples would be density, color, temperature, chemical reactivity, etc.
What is a flame tested used for?
To identify an unknown sample by its emission spectrum
What procedures would you do if you wanted to calculate the density of an unknown substance?
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.
How would you find the density of an unknown liquid if you have all of the laboratory equipment that you need?

How do you calculate density using a formula?
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
Density can be determined using the formula?
I have no clue. Sorry. :( ^^ Ignore that ^^ I think Density = mass/volume.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
