Answer:

We assume you are converting between moles CaCl2 and gram. You can view more details on each measurement unit: molecular weight of CaCl2 or grams This compound is also known as Calcium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles CaCl2, or 110.984 grams.

In at least 4 complete sentences, describe the similarities and differences between Avogadro's Law and Charles' Law.
viktelen [127]

answer

Avogadro's law states that, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles present. In other words, equal volumes of gases at the same pressure and temperature contain the same number of molecules - this is true regardless of their physical properties or chemical nature.

This number of molecules is

6.022

⋅

10

23

and is known as Avogadro's number,

N

A

.

Matematically, Avogadro's law can be written like this

V

n

=

c

o

n

s

t

, or, better yet,

V

n

=

2

n

.

Avogadro's law, as well as Boyle's law and Charles' law, are special cases of the ideal gas law,

P

V

=

n

R

T

. If temperature and pressure are kept constant, and knowing that

R

is of course constant, then

P

V

=

→

n

=

T

→

=

P

=

, which represents Avogadro's law.

The ideal gas law can also be written to incorporate

N

, since the number of moles are actually the number of molecules divided by Avogadro's number

P

V

=

N

N

⋅

R

, where

represents the number of molecules.

The graph below shows the volume and the mass of four different substances at STP.
sladkih [1.3K]
The formula of density is mass / volume

This means that
- high mass, low volume = high density
- high mass, high volume = so-so
- low mass, high volume = low density

From the graph shown, 
D has the lowest density because it has low mass yet high volume.

If 2.27 moles of bromine react with excess phosphorus, how many moles of phosphorus tribromide will be produced
zalisa [80]

Answer:

The answer to your question is 1.51 moles of PBr₃

Explanation:

Data

moles of Br = 2.27

moles of PBr₃ = x

Balanced chemical reaction

                   2P   +   3Br₂  ⇒   2PBr₃

             Reactant      Element     Products

                   2                  P                 2

                   6                  Br                6

-Use proportions to find the answer

              3 moles of Br₂ ------------------  2 moles of PBr₃

         2.27 moles of Br₂ ------------------  x

               x = (2.27 x 2) / 3

               x = 4.54 / 3

              x = 1.51 moles
