b. KCl: 2.7 mM
c. Na2HPO4: 10 mM
d. KH2PO4: 1.8 mM
e. MW NaCL= 58.44 g/mol
f. MW KCl = 74.55 g/mol
g. MW Na2HPO4= 141.96 g/mol
h. MW KH2PO4= 136.09 g/mol

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.

The molar mass of nickel(ni) is 58.7 g/mol. how many moles are in an 88 gram sample of nickel?

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
