Since it is given that molarity is 280 M volume is 500 ml or 05 L and molar mass of KI is 166 gmol. Mass molarity x molar mass x volume of solution 280 mol L. In an aqueous solution NH3 turns to NH4OH and the molar mass is 3504grmol not 17 grmol.
So 1 M means 3504gr in a liter of water and because the solution concentration is 25 the amount of. It has a molar mass of 99 gmol. Analysis of a sample shows that it contains 243 carbon and 41 hydrogen.
What is its molecular formula. Determine the empirical and molecular formula for chrysotile asbestos. Chrysotile has the following percent composition.
2803 Mg 2160 Si 116 H and 4921 O. The molar mass for chrysotile is 5208 gmol. Polymers are large molecules.
