Amixture contains only sodium chloride and potassium chloride. a 0.1586-g sample of the mixture was dissolved in water. it took 22.90 ml of 0.1000 m agno3 to completely precipitate all the chloride present. what is the composition (by mass percent) of the mixture?

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots
