According to VSEPR theory, the molecule PF6- has how many regions of electron density around the central atom (how many electron
anygoal [31]

Answer : The electronic geometry and the molecular geometry of the molecule will be octahedral.

Explanation :

Formula used  :

\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

The given molecule is, PF_6^-

\text{Number of electrons}=\frac{1}{2}\times [5+6+1]=6

The number of electron pair are 6 that means the hybridization will be sp^3d^2 and the electronic geometry and the molecular geometry of the molecule will be octahedral.

How many ml are in 1.25 l of a intravenous solution of 0.9% sodium chloride?
sweet-ann [11.9K]

Mass % of NaCl = 0.9 % (m/v)

Density of 0.9 % NaCl is about 1.0 g/mL

Volume of NaCl in mL :

1.25 L solution * \frac{1000 mL}{1 L} * \frac{0.9 g NaCl}{100 mL solution}*\frac{1 mL}{1.0 g NaCl}

= 11.25 mL NaCl
