What is the molarity (m) of a solution prepared by dissolving 15.0 grams of na3po4 in enough water to make 250.0 ml of solution?

Answer : The molarity of the solution is, 0.365 mole/L

Solution : Given,

Mass of (solute) = 15 g

Volume of solution = 250 ml

Molarity : It is defined as the number of moles of solute present in one liter of the solution.

Formula used :

Therefore, the molarity of the solution is, 0.365 mole/L

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

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.
