What is the molarity of 141.83g of NaClin 40L of solution?

Molar mass of KMnO4= 158.0 g Use this number to convertgrams to moles. moles of KMnO4= 23.7 g KMnO4x (1 mol KMnO4/158 grams KMnO4) moles of KMnO4= 0.15 moles KMnO4 Now the liters of solution is needed. Keep in mind, this is the total volume of the solution, not the volume of solvent used to dissolve the solute.

true

hope that

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
