448/168 = 2.666 (rounded, repeating)
Refer to the definition of density: density = mass / volume. Also, each substance has its characteristic density, independent of its size. A pound of cement will have the same density as a ton of cement. And cement is more dense than rice, regardless of how big a chunk of each you take.
The word chunk has one syllable.
A Chunk
Oh, dude, 2.7 square cm is like the size of a small square with sides that are each about 1.6 cm long. It's not huge, but hey, it's big enough to cover a decent chunk of space on a piece of paper. So, yeah, that's the size of 2.7 square cm for ya.
Data means chunk of information. When lots of data store in single space then it's called file.
Platinum, because his density is greater.
No density if a characteristic of matter. Density can vary with temperature and pressure, but a chunk of something twice the volume of another chunk of the same substance will weigh twice as much because the two chunks have the same density.
Unknown: Volume of chunk of copperKnown:density = 8.94g/cm3 (Wikipedia)mass of irregularly shaped chunk of copper = 1.5kg = 1500gEquation:density = mass/volumeSolution:volume = mass/density = 1500g/8.94g/cm3 = 167.8cm3 = 170cm3 (rounded to two significant figures)
density of concrete (rho)=2400kg/m^3, rho=mass/volume, volume=mass/rho, volume=24/2400 (4/3)*pi*r^3=(volume given)-volume=.02-.01=.01 Solve for r and your done.
To find the mass of the sulfur, we need the volume of the sulfur sample. If we have the volume, we can multiply it by the density of sulfur to calculate the mass. Without the volume of the sulfur sample, we cannot determine its mass.
Mass of silicon = 8.763 (grams? tons?) Volume of silicon = 28.76 - 25.00 (cc? cubic meters?) = ..... Density = Mass of silicon divided by Volume of silicon. = ....... gms/cc? tons/cubic-metre?
The mass and volume of aluminum are related by density: mass = volume x density and density depends upon temperature and pressure. Aluminum has a density of 2.70 grams per cubic centimeter in its solid state. In its liquid state, Aluminum has a density of 2.375 grams per cubic centimeter.
The amount of substance per unit volume or the number of moles of a substance per unit volume is called its MolarityI think you meant to say "What is the MASS of substance in a given volume called?", meaning what name is given to the mass-per-unit-volume of a substance, i.e. the mass of a chunk of it divided by its volume. The is density.
The density is 20 kg/m3
Refer to the definition of density: density = mass / volume. Also, each substance has its characteristic density, independent of its size. A pound of cement will have the same density as a ton of cement. And cement is more dense than rice, regardless of how big a chunk of each you take.
That depends. If the two different silver masses contain different impurities, then the answer is yes, but it would very only slightly so as to be almost negligible. In general, any two or more objects that are made up of the same substance have the exact same density. The size of the sample is not a factor of its density (assuming the size increase is not due to heat), since density = mass/volume.
The iron chunk will be denser and heavier than the aluminum chunk due to the higher density of iron compared to aluminum. Iron is also more susceptible to corrosion compared to aluminum.
