who can tell me the density of  5-iodouracil?

Have you tried the Merck Index?

Yes, it is true that the density of a solution is different of solvant but tjis difference is small ; So , i propose to dissove 40g of amyl acetate in a liter of water if that acetate is a solid. If that acetate is aliquid the total volume will be 1.04 l and you must use 47 cc tp water

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.

I found a web site with a lab on how to figure out releative density of a given liquid hope it helps.  It has all the instructions and materials needed listed on the site

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.

The CRC Handbook of Chemistry and Physics has all kinds of good information like that (although it is pricey).\n\nOr, search the web for the specific liquid of interest.

Chemical laboratory supply houses carry it.  Try Alfa Aesar, they have it:\n\nhttp://www.alfa.com

You can use Aldrich, which will give you a sample spectra of the compound. It would be very useful for identification based on a comparison of the fingerprint region (<900 cm-1)\n\nAny Organic book worth its salt will have typical vibrational frequencies. You can also do a yahoo search to get them.

Density is mass divided by volume. 25 divided by 5 = 5 g/mL.\n\nDensity = 5 g/mL.

When I was growing up we used DCPIP (Di-Chloro-Phenol-Indo-Phenol) to test for Vit C.\n\nWhere did you get the OJ from? Some have added vitamins...\nHow freshly prepared was the Iodine tincture?\nDid you do your own dilutions of titrant?\nCould the Iodine have reacted with a carbohydrate present in the OJ (like it does with starch)?

you would also use one of the following equations typically depending on the other information your given, but for sure, you need to look up its chemical composition. (ex: water is H2O)\n\nif youre given concentration:\nconcentration=moles/volume\nmoles=mass/molar mass\nmass=moles*molar mass\nmass=(concentration*volume)(molar mass)\nkeep in mind molar mass can be found by adding and multimplying as necessary the atomic masses of each element in the compound.\n\nif youre given density (which i bet you can easily look up on google or something if youre not given that information):\ndensity=mass/volume\nmass=density*volume

Suppose we have pure HTO and DTO. The molecular masses are 20 and 21 compared to 18 for H2O. The density is therefore 20/18 = 1.111 g/cm3 and 21 / 18 = 1.167 g/cm3 respectively.

Water has its highest density at 4 deg. C.\n\nYou might try a Yahoo! search next time.  That's how I found the info.\n\nTake care,\nDavid Roth\nwww.tutor-homework.com

Density = mass/volume

Measure concentration. Use a dummy (with water only) measuring that with a LabPro probe. Then compare that to a certain volume of a variable soft drink. I did this in high school, hope it works!
