What is an Angstrom
And Angstrom is a unit of length measured 10 to the -10 m the Angstrom is convenient because atomic radius and the bond lanes are typically around one or three instruments.
The density of a substance is this mass per volume
Density P equals mass divided by volume or M overview. Yes our unit density is measured in kilograms per cubic meter.
What is molecular formula
Molecular formula is a compound give an identity and number of atoms in the each molecule of the compound
Name some polyatomic ion’s
Basic polyatomic ion’s are ammonium in H for and hydronium H30
Acidic polyatomic ion’s or acetate bicarbonate cyanide hydroxide nitrate nitrite and perchlorate.
What is the formula and molecular weight
The chemical formula we can figure out the formula way which is a sign of the atomic plates of all the items in the mouth.
What is the atomic mass unit
The atomic mass unit is the abbreviation for weight is a popular term which is also known as mass one atomic mass unit is by definition equal 1-12 the mass of an Adam of carbon 12.
What is the molecular weight
The atomic mass unit may not be explicitly included when I compounds exist as a discrete molecule the term molecular weight is usually used instead of formula weight. The molecular weight is adding up all the formula weight per element in each molecule.
What is the mole.
A mole is a simply a particle number of thanks like 1000 is in a group of 12 things one mole is anything contains 6.02×10 to the 23rd entities.
How are moles calculated
Bulls are calculated taking the mass in grams divided by the molecular way. This is most often utilized by Avogadro’s number.
What is Avogadro’s number
6.022X 10^23
What is the composition by mass of a given molecule.
How this works out is that you take the empirical formula of a substance given the molecular way divided by the total weight of a molecule would give you the percentage of each Element in each molecule.
Section 3.9 is concentration or molarity what is molarity
Molarity express is a concentration of a solution in terms of multiple saw you heard volume in liters of solution Mary equals number of moles of saw you divided by number of leaders of solution.
