ppm is parts per million and thus a concentration. It can not be calculated from molecular weight.

Calculate the empirical formula weight. Find the ratio of the molecular weight to the empirical formula weight. (n= molecular weight/ empirical formular weight). Multiply each subscript of the empirical formula by n.
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
The atomic weight of potassium is 39,0983 g.The atomic weight of chlorine is 25,45 g.The molecular weight of potassium chloride (K + Cl) is 74,5483 g.
Ti = 1 x 47.867 = 47.867 O = 2 x 15.999 = 31.998 -------------------------------- Molecular weight = 79.865g/mol
To convert ppm mass basis to ppm volume basis: ppmm/molecular weight x 22.4 = ppmv
the given molecular weight is divided by volume
10 ppm mole multiply by molecular weight of water then divided by sample density

Ppm basically means milligrams per litre. So the volume does not need adjusting. You just need to multiply by the molecular weight. However, you havent stated the compound so we cannot work out the molecular weight.
Molecular weight is just an older term for molar mass. They are the same.
Calculate the empirical formula weight. Find the ratio of the molecular weight to the empirical formula weight. (n= molecular weight/ empirical formular weight). Multiply each subscript of the empirical formula by n.
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
So here, you have to divide by the molecular weight. The molecular weight is 146g/mol. 16.3/146 is 0.11164 moles
The atomic weight of potassium is 39,0983 g.The atomic weight of chlorine is 25,45 g.The molecular weight of potassium chloride (K + Cl) is 74,5483 g.
Ti = 1 x 47.867 = 47.867 O = 2 x 15.999 = 31.998 -------------------------------- Molecular weight = 79.865g/mol
molecular mass N2o is 44
