using water displacement because it doesnt float on water and it doesnt dissolve in water
You must know the mass and density to find volume. You must know the mass and volume to find density. You must know the volume and density to find mass. OF ANYTHING! at room temp. that is. This changes with pressure for gases. See the gas laws.
density is the constant found by dividing the mass (in grams) by the volume in centimeters cubed (sometimes milliliters). other units are possible but are not common in science classes. every substance has a set density, that never changes. the more you have in mass, the same higher proportion of volume comes with it. the density of pure water is 1.000 gram per cm3 the density of copper is 8.960 grams per cm3
Just stating "contaminated" tells us nothing. What the water is contaminated with will determine the pH level - contaminate the water with an acidic substance and the pH will be higher than if you contaminate ith with an alkali.
Osmium has. Gold and iridium are up there too. Lead isn't even close.
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. The molecular formula and the accurate molar mass would be N14O35.
What would be the density of an object that has a volume of 25 cm3 and 5 grams?
To find the density of a substance you need the mass as well as the volume. The mass is 10 grams so all you need to do is find the volume. It is easiest to do this using displacement of water in a graduated cylinder. I would take a 100 mL graduated cylinder and fill it up with water to.. lets say.. 50 mL. Furthermore, very slowly add the granular salt to the graduated cylinder using a funnel, being sure not to spill any. Now read how much is in the graduated cylinder. Second value - first value = volume of salt. Divide 10 grams by the volume. Answer would be in ___grams/mL^3
Weigh the piece of maple (you've indicated it is about 10 grams) Completely submerge it in a liquid and measure the volume of liquid displaced Density = mass/(volume displaced) or about 10g/(volume displaced)
Linear density, perhaps?
You would first determine the mass of the egg. Then you would need to determine the volume of the egg through water displacement. Then you would need to divide its mass by its volume, and that will give you the density.
Depends on what it is. Like density of 10 grams of flowers would be different than 10 grams of lead. Need more information.

well you have to think you would weigh this using grams so the density of a foam block is "Grams per cubic centimeters"
Determine the mas and the volume.
As density is measured in mass per unit volume, the question is unanswerable as written. We need to know "density of 2.5 grams per what measure of volume" in order to answer the problem.
This question makes no sense.Grams are a measure of weight;whereas centimeters are a measure of length.weight and volume (which would be cubiccentimeters) are related by the density of the substance.So that if the density of the substance was known, then multiplying the density (in grams per cubic centimeter) by the volume (in cubic centimeters) of the substance would give the weight (in grams) of the substance.
Grams is a measure of mass and milliliters is a measure of volume. The way they are related is through the equation: density= mass/ volume. Therefore you would need to find the density of the substance in order to convert the units. If you find the density then you would multiply the density and 47 grams to find the volume.
