How do you find the mass, volume, and density of an object, and what formulas and Sl units are used for each? Would equal volumes of two different substances have the same or different masses? Why?

$"Density,"$ $rho="Mass"/"Volume"$, and thus it has the units of $g*mL$ or $g*cm^-3$.

For a given substance, its tells you the mass occupied by one unit of volume of that substance. In essence, is a measure of how well the molecules of...

$rho, "density" ="Mass"/"Volume"$. The object displaces a volume of $(50-30)*mL =20*mL$. Given that we know the mass the calculation of the density is now easy.

$"Density"$ is an $"intensive property"$, a property that depends on the nature of the material, unlike the $"extensive properties"$ such as mass and volume, which are determined by the extent...

$rho,"density"="mass"/"volume"$ Given constant $"volume"$, the lower the mass the smaller the $"density."$

The formula for is $"density" = frac("mass")("volume")$. We need to double the volume, i.e. multiply it by $2$. But in order to multiply one side of the equation by a...

$"Protium"$, $""^1H$, and $"deuterium"$, $""^2H$, are two of the most abundant substances in the universe. Of course, they are that differ in the number of neutrons present in their nuclei....

If there are two an element $"Average atomic mass" = "mass"_axx "fract"_a + "mass"_b xx "fract"_b$ In the given problem about Hafnium, 5 isotopes have been given. Extending the...

The $"Average Atomic Mass"$ of an element is defined as "the weighted average mass of all naturally-occurring (occasionally radioactive) of the element." (and hence the name "average") [1] Dividing the...

So if I start with a 10 g mass of reactants, from all sources, AT MOST, I can get a 10 g mass of products. In practice, I am not...
