What is the molecular weight of a compound with pressure 750mm Hg volume 275ml weight 0.920g and temperature of 100c?
In order to find the molecular weight of a compound the components would have to be converted. The conversions are 750mmHg to .987atm, 275ml to .275l, the weight stays at .920g, and the temperature from 100c to 373.15k. These numbers plugged into the equation MW=mRT/(PV) the molecular weight is found to be -.63.
How do you find molecular mass if specific volume is given?
This is easy if a gas. The weight of a volume of 22.41 L will give the molecular mass.
How do you find the molecular formula for a compound with mass of 78amu?
You can't without more information. You cannot go from the molecular weight of a compound to its formula without more information about what atoms it contains.See the Related Questions link to the left for a more detailed discussion of this.
How can one easy calculate the kinetic diameter or an equivalent measure of a given molecule?
Firstly, calculate the molecular volume by dividing the product of molecular density and the molecular weight by the Avogadro number. Then take a third root of the volume, the found value is the atomic radius. Then multiply it by 2 to find the diameter.
Where on the periodic table will you find the elements in a molecular compound?
Molecular compounds contain nonmetals, which are on the far right of the periodic table.

How many micromoles is 20 micrograms?
You haven't specified the molecular weight, or even the compound in question. If you find this out, divide by the molecular weight to get your answer.
How do you find molecular mass if specific volume is given?
This is easy if a gas. The weight of a volume of 22.41 L will give the molecular mass.
Find the molarity?
Molarity = Grams/(Molecular Weight X Volume)
How do you convert molecules to gram?
You first divide the amount of molecules by avagadros number (6.022x10^23) to find out how many moles you have. Then you find out the molecular weight of the compound. You multiply the number of moles by the molecular weight to give you your weight in grams.
0.871 moles is how many grams?
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
If you have molecular weight how can you find equivalent weight?
Equivalent weight ofc11h17n3os2 from molecular weight271.402
How do you find out molecular wt using density?
I'm not exactly positive. But if you know the volume in grams and the mass (giving you density), then you should be able to figure out the molecular weight. The mass is the same as the molar mass, which I would assume is the same as the molecular weight, but I'm not positive.
The molecular mass of the compound is 132 amu. What is the molecular formula?
This is impossible. In order to find this you must know the elements in the compound

How do you find molecular fomula?
The molecular formula is established only after an accurate chemical analysis of the compound.
