Is atomic weight a whole number or not a whole number
steposvetlana [31]

Answer:

Atomic mass of an element is not a whole number because It contains isotopes. For example, chlorine has two isotopes 1735Cl and 1737Cl with natural abundances in the approximate ratio of 3:1. Hence, the average atomic mass of chlorine is approximately 35.5 g/mol.

Hope this helps! If so please mark brainliest and rate/heart if it did to help my account out!!

How many electrons are transferred between the cation and anion to form the ionic bond in one formula unit of each compound? (1
kodGreya [7K]

The number of transferred electrons to form the ionic bond in one formula unit of each compound is as below

NaCl = 1 electron

CaS = 2 electrons

BaO= 2 electrons

KBr=1 electrons

LIF = 1 electron



explanation

ionic bond is formed between a metal and a nonmetal . This bond is formed when electron are transferred between cation and anion. To know how many electrons transferred you look the oxidation state of the metal.


for example 

in NaCl only one electrons is transferred since Na is in oxidation state of +1. Na donate the one electron to Cl to form an ionic bond.  Ba  is in oxidation state  of 2+ and hence it  donate the two electrons to O to form ionic bond.

How many moles of barium chloride are present in 6.5l of a 3m solution
Contact [7]

Answer:

The answer to your question is 19.5 moles

Explanation:

Data

moles = ?

Volume = 6.5 l

Molarity = 3 M

Molarity is a unit of concentration that relates the number of moles by the volume (liters).

Formula

Molarity = moles / Volume

-Solve for moles

moles = Molarity x Volume

-Substitution

moles = 3 x 6.5

-Result

moles = 19.5
