how much is the density of 5-iodouracil?
440959
Below is a link to the MSDS (Material Safety Data Sheet) for this compound, which is actually 2,4-Dihydroxy-5-iodopyrimidine, but curiously it does not list the density.\n\nHave you looked in the Merck Index?

Half carat is equal to 100mg and diamond density can be taken as about 3.5g/cc. From this, the size would be approximately equal to a cube of 3mm x 3mm x 3mm or so.

The molecular mass of Iodomethane (CH3I) is 141.94 g/mol.\n\n1g/141.94g/mol = 0.007 moles.\n\n.007 x 6.02 x 10^23 = 4.21 x 10^21 molecules.

Density = mass / volume\nSo 514 g/500mL = ??? g/mL\nAnd that's all of your homework I'll do for you. ;)

Density = mass / Volume\n\nYou are given the mass of the cyllinder (m = 4 kg).\nYou are given the dimentions of of the cyllinder which you can then use the find the volume.\n\nThe volume of a cyllinder = (pi*r^2)*h\nwhere pi is the constant pi (the ratio of the circumfrance of a circle to its diameter, ~3.1415), r is the radius, and h is the height.\nUsing this formula, I calculate the volume of the cyllinder to be about 9425 cm^3.\n\nD = m / v\nD = 4000 g / 9425 cm^3\nD = 4.24 E-1 g/cm^3 or 424 kg/m^3\nThis is a low density by comparison to many other things, for example, water has a density of about 1 g/cm^3.\n\nNext Time, do your own home work.

Refrigerant 123 is more correctly known as 2,2-dichloro-1,1,1-trifluoroethane.  Density is 1.4638 g/cm3

The density is 0.357 g/mL. This is because specific gravity is the ratio of the density of the unknown liquid to the density of water, 1.0 g/mL.\n\nIf, say, you wanted to know the density of the liquid in pounds per gallon, you would multiply 0.357 by the density of water, which is 8.320 lb/gal

Osmolarity is in units of mol/L, while osmolality is in units of mol/kg. If the solvent for the solution is water, then there is no need for conversion, since 1 L of water weighs about 1 kg. So 0.5 molar solution of NaCl or any other substance will also be a 0.5 molal solution if the solvent is water.\n\nIf the solvent is not water (alcohol, benzene, etc) then you must convert the mol/L into mol/kg. The easiest way to do this is to find out what the solvent's density is.\n\nFor example: imagine you have a 0.500 molar solution of napthalene dissolved in benzene. That means that there is 0.500 moles of napthalene for every 1 liter of benzene (since we are talking about molarity). The density of benzene is 0.8765 g/ml, which is equivalent to 0.8675 kg/L. So use the density to help you solve for the molality:\n\nMOLARITY / DENSITY = MOLALITY\n\nIn our example:\n\n0.500 mol napthalene/L       \n------------------\n0.8675 kg/L\n\nThe liters cancel out and you are left with the units of mol/kg (molality). In this case, the answer is 0.576 mol/kg.

Name: iodine \nSymbol: I \nAtomic number: 53 \nAtomic weight: 126.90447 (3) \nCAS Registry ID: 7553-56-2 \n Group number: 17 \nGroup name: Halogen \nPeriod number: 5 \nBlock: p-block \n \nHere is a brief description of iodine.\n\nStandard state: solid at 298 K \nColour: violet-dark grey, lustrous \nClassification: Non-metallic \nIodine is a bluish-black, lustrous solid. It volatilises at ambient temperatures into a pretty blue-violet gas with an irritating odour.\n\nIt forms compounds with most elements, but is less reactive than the other halogens, which displace it from iodides. Iodine exhibits some metallic-like properties. It dissolves readily in chloroform, carbon tetrachloride, or carbon disulphide to form beautiful purple solutions. It is only slightly soluble in water. Iodine compounds are important in organic chemistry and very useful in medicine and photography. Lack of iodine is the cause of goitre (Derbyshire neck). The deep blue colour with starch solution is characteristic of the free element. It is assimilated by seaweeds from which it may be recovered, and is found in Chilean saltpetre, caliche, old salt brines, and salt wells.\n\nYou can never know too much :)

I think you mean .25 mol/L or a .25 Molar solution.\n\nSince you are only making .5L (500 mL) you only need .125mols\n\n.125 mols X 58.44 g/mol = 7.3 grams\n\nBy the way, if you are a teacher, it is a lot easier (and much less stinky) to get DNA from raw (not toasted!) wheat germ.  \nhttp://gslc.genetics.utah.edu/units/activities/wheatgerm/

Well silver density is 10.5 Kg/dm³. but rugby ball volume is quite difficult to calculate... I made an aproximation calculated as two opposite cones taking the max. size and it gave me a little more than 3 dm³, so the wheight would be about 31.5 Kg. Actually even more as the ends of the cones in the ball are rounder so they have a bigger volume...
