8 0

Answer:

11.76% by weight in salt

Explanation:

concentration = mass of solute / mass of solute + mass of solvent

mass of solute = 20 grams

mass of solvent = 150 grams

mass of solute + mass of solvent = 20g + 150g = 170g

concentration (weight %) =  (20g / 170g)100% = 11.76% by weight in salt.

What geometry does VSEPR predict for the central atom in NCl3
Archy [21]

Answer:

Tetrahedral electron geometry and trigonal pyramidal molecular geometry.

Explanation:

The Lewis structure is shown in Figure 1.

The central N atom has three bonding pairs and one lone pair, for <em>four electron groups</em>.

VSEPR theory predicts a tetrahedral electron geometry with bond angles of 109.5°.

We do not count the lone pair in determining the molecular shape.

The molecular geometry is trigonal pyramidal (see Figure 2).
