If 0.220 molmol of a nonvolatile nonelectrolyte are dissolved in 3.70 molmol of water, what is the vapor pressure PH2OPH2O of th
Masteriza [31]

Answer:

Vapor pressure for solution is 22.4 Torr

Explanation:

P° → Vapor pressure of pure solvent

P' → Vapor pressure of solution

Formula for lowering vapor pressure is: P° - P' = P°  . Xm

Xm is the mole fraction. Let's determine it:

0.220 mol of solute + 3.70 mol of water = 3.92 total moles

Mole fraction for solute → 0.220 / 3.92 = 0.056

23.8 Torr - P' = 23.8 Torr  . 0.056

P' = - ( 23.8 Torr  . 0.056 - 23.8 Torr ) → 22.4 Torr

A pile of Mgo dust is known to contain 2.082 mol. How many molecules are there?
nlexa [21]
Every one mol of MgO is 6.022 x 10^23 molecules (Avogado’s Number) So, you multiply 2.082 mol of MgO with 6.022 x 10^23 molecules. Hope this helps!

Draw a Lewis structure for SF4 that has minimized formal charges. Include all nonbonding electrons and any nonzero formal charge
gayaneshka [121]

Answer:

See explanation and image attached

Explanation:

The compound SF4 is sulphur tetraflouride. It has a zero formal charge and has a total of 34 valence electrons.

The central atom in the molecule is sulphur in an sp3d hybridization state hence the molecule has a trigonal bipyramidal electron geometry. Since it is a molecule of the sort AX4E; it gives a see-saw molecular shape.

The structure of the molecule is shown in the image attached to this answer.
