What are the units for mass, volume, and density?
And thus $rho("density")="mass"/"volume"$. Because the $m^3$ is a very large volume $(1000*L)$, chemists typically use $g=10^-3kg$ to express mass, and $dm^3$ (or $"litres"$) to express volume. $1*dm^-3=(1xx10^-1m)^3=1xx10^-3*m^3=1*L$. Chemists also...

A foam material has a density of $175$ $g$$/L$. What is its density in units of $lb$$/ft^3$?
Let's break the answer down into three parts: $color (brown) ("First,"$ we're going to convert grams to pounds using this conversion factor: $color(white)(aaaaaaaaaaaaaaaaa$ 1 pound = 453.592 grams $color (purple)...

If an object has a density of $8.65$ $g$$/cm^3$, what is its density in units of $kg$$/m^3$?
Your goal here will be to use two conversion factors, one to take you from grams to kilograms and one to take you from cubic centimeters to cubic meters....

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?
Mass is measured in $"kg"$, volume in $"m"^3$ and mass density in $"kg"$ $"m"^-3$. The formula for density is given by the following equation: $rho=m/V$ where $rho$ is the density,...

A mass of mercury occupies 0.95 L. What volume would an equal mass of ethanol occupy? The density of mercury is 13.546 g/mL and the density of ethanol is .789 g/mL?
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...

569 g salt water solution is added to a beaker. If the solution has a density of 1.19 g/mL, what is the volume of this solution?
$rho,"density"$ $=$ $"Mass"/"Volume"$ Thus, $"volume"$ $=$ $"Mass"/rho$ $=$ $(569*cancelg)/(1.19*cancelg*mL^-1)$ $=$ $??mL$. Note the dimensional consistency. I wanted a volume; and the units of the calculation cancelled to give me an...

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. When the rock is cut in half what is the volume and density of each piece?
$rho="Mass"/"Volume"=(16*g)/(8*cm^-3)$ $=$ $??*g*cm^-3$ And the volume of each piece is $??*cm^3$.

What is the volume of a solution that has a mass of $21.0*g$ and has a density of $19.3*g*mL^-1$?
$"Density,"$ $rho$ $=$ $"Mass"/"Volume"$, and we use this quotient. We have $rho$ and $"mass"$. And thus we perform the operation: $"Volume"$ $=$ $"Mass"/rho$ $=$ $(21.0*cancelg)/(19.3*cancelg*mL^-1)$ $=$ $??*mL$. Dimensionally, this is...

How do you find the mass of a solution if you know the volume and identity of the solute added, the density of the solvent, and the concentration of the solution?
If $rho=1.12*g*mL^-1$, then a $1*L$ volume of solution has a mass of: $1*cancelLxx10^3*cancel(mL)*cancel(L^-1)xx1.12*g*cancel(mL^-1)=1.12xx10^3*g$ $-=1.12xxcancel(10^3)*cancelgxxcancel(10^-3)*kg*cancel(g^-1)$ $-=1.12*kg$. Note that this is a measurement SOLELY of $"density"$. This is likely an aqueous solution,...

What is the mass percent of sucrose in a solution obtained by mixing 225.0 g of an aqueous solution that is 6.25% sucrose by mass with 135.0 g of an aqueous solution that is 8.20% sucrose by mass?
And from the initial , we have to first extract the mass of , and then divide this by the combined mass of solutions. And thus we go thru the...
