Answer is: 1) formula mass.

Formula weight is given in atomic mass units (amu).

The unified atomic mass unit (amu) is a standard unit of atom mass.

Atomic mass of carbon atom is 12.01 amu.

Atomic mass of hydrogen atom is 1.01 amu.

Atomic mass of bromine atom is 79.9 amu.

In chemical compound C₃H₆Br₂ there are three carbon atoms, six hydrogen atoms and two bromine atoms.

M(C₃H₆Br₂) = 3 · 12.01 amu + 6 · 1.01 amu + 2 · 79.9 amu.

M(C₃H₆Br₂) = 201.89 amu; formula mass of one molecule.

determine the strongest intermolecular force in pure samples of each of the following: a. h2o b. cf4 c. co2 d. ph3
Virty [35]

The strongest intermolecular force is the hydrogen bond in water (H2O).

What is intermolecular force?
Intermolecular forces
are those that develop between the molecules of a substance and can cause them to attract or repel one another. The type of intermolecular force that is present in the matter determines all of the material's physical and chemical properties.

Interactions between dipoles
Involvements of Ion-Dipoles
Dipole Interactions Induced by Ions
DID Interaction: Dipole Induced DID
London Forces or Dispersion Forces
These five intermolecular force types are listed above.


The intermolecular forces were in this order:
The strongest force is ion-dipole force.
the hydrogen bond
Force between dipoles
the least powerful is the dispersion force.
The strongest intermolecular force is therefore the hydrogen bond in H2O.

Fill in the sentences below to explore the process by which a storm becomes a hurricane. some terms may be used more than once.
Reptile [31]

Answer:

The sentences which are made by the given sentences are as :

Wind speeds are below 38 miles per hour, this feature represents the tropical depression.

Explanation:

Here in the question it has been mentioned to form the sentences with the given one:

  • Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
  • A tropical disturbance leads to an array of clouds which are disorganized    also there are thunderstorms with no rotation or little rotation with it.
  • When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
  • 74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
  • When the storm reaches a tropical storm stage it gets its name.
  • All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.

These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
