The of pure water is 1 gram per 1 milliliter or one cubic cm. By knowing the density of water we can use it in dilution equations or to calculate the specific gravity of other .

It can also help us determine what other substances are made of using the water displacement experiment. This is done by observing how much water is displaced when an object is submerged in the water. As long as you know the density of the water, the mass of the object being submerged and the volume of increase you can calculate the density of the object.

This was done by the great Archimedes in discovering what composed the kings crown.

Why would you get a more accurate measure of the measure volume of an irregular solid by using displacement instead of measuring with a ruler?

And we don't even need to use an irregularly shaped solid, we could compare the methods with a sphere. Unless I had a pair of calipers, I could not measure...

Rebecca has samples of different types of metal. She wants to measure the samples to find out the density of each metal. First, she measures the samples' volumes. Now she needs masses. What tools should Rebecca use to measure her samples' masses?

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

9. The density of water is 1.0 g/mL. What is the density of water in pounds/gallon?

Use "Dimensional Analysis" to determine what "conversion factors" you will need before you do the math. $g/"mL" xx "??"/"??" = "lbs"/"gal"$ We need a mass conversion unit ($g to "lbs"$)...

Carmen is heating some water and trying to measure the temperature of water using a Celsius thermometer. What measurement can she expect once the water begins to boil?

Celsius is defined as the scale in which water freezes at $0^o$ and boils at $100^o$.

An 81-kg person puts on a life jacket, jumps into water, and floats. The jacket's volume is $3.1*10^-2m^3$ and is completely under water. The volume of the person’s body that is under water is $6.2*10^-2m^3$. What is the density of the life jacket?

The idea here is that you need to find the mass of the life jacket by using the total mass of water displaced by the person and his life jacket....

An 77-kg person puts on a life jacket, jumps into water, and floats. The jacket's volume is $2.7*10^-2m^3$ and is completely under water. The volume of the person's body that is under water is $6.7*10^-2m^3$. What is the density of the life jacket?

Since the problem provides you with the volume of the jacket, you will have to focus on find its mass by using the total mass of water displaced by the...

The density of water is 1.00 g/mL. Carbon tetrachloride is insoluble in water. Would carbon tetrachloride float on water or sink beneath water when they are combined?

of carbon tetrachloride at ambient conditions is approximately 1.5 g/ml, so for a given volume carbon tetrachloride has a higher mass than water. So when combined the carbon tetrachloride...

The density of mercury is 5,427 $kg$$/m^3$. If the density of water is $1.0$ $g$$/mL$, will mercury float or sink in water?

The density, $rho$, of mercury $=$ $13,593*kg*m^-3$; it is $13.6*g*cm^-3$ in more accessible units. Anyway, mercury metal is pretty dense stuff. If you ever found a pool of mercury, you...

A graduated cylinder contains 225 mL of water. What is the new water level affer 30.2 g of silver metal with a density of 10.5 g/mL is submerged in the water?

Well, we work out the water displaced by the silver........by calculating the volume of the silver nugget using the . $"Density"(rho)$ $=$ $"Mass"/"Volume"$ Thus $"Volume"="Mass"/rho$ $=$ $(30.2*g)/(10.5*g*mL^-1)$ $~=$ $3*mL$. This...

The density of water is 1.00 g/mL at 4°C. How many water molecules are present in 2.46 mL of water at this temperature?

The idea here is that you need to use the of water at $4^@"C"$ and the volume of the sample to find its mass, then use water's molar mass to...
