So the mass of the sample is 50 milligrams and the molar mass is 191.37 grams per mole. Now if I divide the mass sample over the molar mass I should get the number of moles right. If I multiply the number of moles with avogrado's number I should get the number of molecules per milliliter right.
Hi Borek,How do you claculate the mass of a substance of one milliliter?Thanks
Hi Borek,The solid density is about 5.816 grams per cubic centimeter. Do I convert the 50 milligrams to grams and the cubic centimeter to one milliliter?What I know so far is that: 1 milligram = .001 grams, and 1 milliliter = 1 cubic centimeter.
Well the solid density is about 5.816 g per cubic centimeter.
