The molecular weight of it is 386.654g/mol. Convert mass to grams (i.e. 0.0039g). divide mass by molec weight to get 1.0083573x10^-5 moles. Multiply this by avagadros number to get the amount of molecules. this gives you 6.072x10^18 molecules.

The mass is 74,7 mg.
Macromolecules are formed from many simple molecules (monomers) and have a big molecular mass.
This mass is 61,947 g.
The mass of 5,2.e10 molecules of fluorine (F2) is 32,809.10e-13 g.

Molecules are not a force, they have mass.
The number of molecules is 4,993.10e23.
This depends on the mass of nitrogen contained in the balloon.

The mass is 74,7 mg.
The mass is 9,6.10e-22 g for 34 molecules.
Amount of Br2 = mass of sample / molar mass = 160 / 2(79.9) = 1.00mol
567.1 mass is the equal to 56789.0 intergram. XD
The number of molecules is 6,624354943.10e23.
There are 82.102 molecules in 2.3 grams of NH4S02. You divide the molar mass of NH4S02 and multiply by 6.02x10^23.
It really depends on what it is. You need to firstly know what it is, and particularly the molecular mass
