I need help finding density!?
813571
325N/9.8m/s^2=33.16 Kg=33163g\n265N/9.8m/s^2=27.041Kg=27041g\n\n33163g-27041g=6122 g of water displaced.  Since water's density is 1 g/cc it is 6122 ccs displaced by the object, that is it's volume. 33163g/6122cc=4.417 g/cc, that is your density.\n\nIn oil the object weighs 295 N\n295n/9.8m/s^2=30.102Kg=30102g\n\n33163g-30102g=3061 g of oil displaced.  The volume of the object stays the same (unless you add some additional information on pourous material) so if 3061 g are displaced by 6122cc, the oils density is 3061g/6122cc=0.5 g/cc

You must to know the density, d. Then use the formula m = vd and you will know the mass of compound. Divide m by M (molar mass) and this is number of molles, n\n   n = vd/M

the way to find the mass of an object is to divide the volume by the density it would look like this M = D / V

Why not take a page from Archimedes' Eureka! moment?\n\nMeasure the density, then ask a jeweler.

I hope you didn't use the other answer for your homework because those are not density values. They are mass values for a specific volume. There is a big difference. \n\nThe density of gneiss is:  2.6 - 2.9

This is how you do it.\nYou need to find out the mass of hexane first. Calculate the mass of hexane by subtracting the mass of empty beaker from the mass of beaker with hexane. Once you obtain the mass of hexane, divide it by the volume which is 5ml. You will get your density in units g/ml. I hope this was enough help. E-mail if you need more than this.

Dude...the question still can't be answered unless you know the density of grain.  Is that not given?

Finding the density of a gas requires information on pressure, and temperature.  d=pM/RT where d is density, p=pressure in atm, M is molar mass, R is the gas constant, and T is temperature in kelvin.  For a liquid the only factors to calculate density are mass, volume and temperature.  d=m/V...at a given temperature.  For solids the mass and volume are only needed.

You can by multiplying 1/2 of density by 5

Volume = 1/48 * 1*1 = 1/48 cu ft\ndensity = 480 pounds per cu ft\n\nmass = density*volume = 480* 1/48 lb = 10 lb

You should use density to check that out.\nDensity=Weight/Volume

Go back to basics...\n\nDensity = mass / volume\n\nSo for compressible fluids if the volume goes down the density goes up...if the volume goes up the density goes down.  In general then we can say that density of a compressible fluid is inversely proportional to volume.

you cant you have to have mass and volume to find density

Density is mass per volume.   \nDisregard the weight; it's irrelevant.\nUse volume = lenght * width * height (or depth).

Your density will be similar to whatever material makes up the planet.  For instance, Mars is mostly rock, with some iron ore.  I'd guess the density is on the order of 2.5 g/cm3.  Jupiter is made up of mostly dense gases.  I'd guess given the temp, that the density is slightly higher than that of water, like 1.3 g/cm3.\n\nVolume on the other hand.......are you kidding?  You seriously want it in cm3????  You'll run out of room on your paper writing zeros.

i think it has something to do with the density...couldnt tell you exactly tho

Density is mass/volume.  Find its mass by weighing it. Find its volume by immersing it in water and measuring how much water it displaces.  That is its volume.\nDivide mass by volume and you've got density.\nP.
