Alculate the molality of each of the following aqueous solutions: (a) 2.50 M NaCl solutions (density of the solution=1.08 g/mL)

Answer=2.68 m

(b) 48.2 percent by mass KBr solution.

Answer= 7.82 m

what's the equation for it? Because I have the answers

Agas has a volume of 0.7 l at 300 mmhg. what would be the new volume at 900 mmhg

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

The atom fluorine generally will become stable through the formation of an ionic chemical compound by accepting electron(s) from another atom. this process will fill its outer energy level of electrons.
