Is atomic mass and molar mass similar and mass number of particles the same?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why does the molar mass increase by more than one unit when the atomic number increase by one unit?
Because atomic mass is the sum of both atomic number and number of neutrons in an atom.
Is the atomic radius the same as the atomic mass?
no atomic radius is not the same as atomic mass because it is 10 to the power of 10 and atomic mass is different for different elements
What is the difference between atomic weight and atomic mass and molar mass and molecular weight?
The atomic mass is the mass of an atom at rest. This refers to one atom, and is typically measured in so-called atomic mass units, and describes a single isotope of that element. The atomic weight is the abundance-weighted average mass of an element (an average mass of all the isotopes that exist for that element, weighted by how abundant each isotope is in nature). Atomic weight is commonly reported in atomic mass units, as well as in grams per mole. The molar mass is the mass of one mole of something, and can refer to both a single element as well as molecules and other compounds. The molecular weight is essentially the same thing as the molar mass except that, as the name implies, it refers to molecules rather than just elements. The molar mass and molecular weight is typically given in units of grams per mole.The molecular weight of a compound is found by adding the atomic weights of all of the atoms in the compound. Water, for example, has a molecular weight of 18.0152 grams/mole, as there are two hydrogen atoms that each have an atomic weight of 1.00079 g/mole and one oxygen atom with an atomic weight 15.9994 grams/mole.
What is the difference of atomic mass and molar mass?
A mole is the amount of a substance that contains as many atoms, molecules, ions, or other elementary units as the number of atoms in 0.012 kilogram of carbon 12. The number is 6.0225 × 1023, or Avogadro's number. Molar mass is the mass of one mole of a substance.
Is avogadro's number the same as molar mass?
no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
Is atomic mass and molar mass similar and mass number of particles the same?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is meant by expressing atomic weight in grams?
It means that atomic weight is expressed in form of Molar weight. When we write that the atomic mass of an element is X, it means that it is X amu(atomic mass unit) and not X grams. An atomic mass unit is very less as compared to a gram. The molar mass of an element or compound is its same mass as in amu but in grams.
The molar mass of an element is equal to?
The element's average atomic mass.
Which gas effuses faster at the same temperature molecular oxygen or atomic argon?
Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g
What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What does the molar mass of C7H16 and the molar mass of CaCO3 have the same number of?
342.3
Do isotopes have the same atomic number and the same atomic mass?
No: They have the same atomic number but not the same atomic mass.
Is molar mass and formula mass the same?
yes it is
Why does the molar mass increase by more than one unit when the atomic number increase by one unit?
Because atomic mass is the sum of both atomic number and number of neutrons in an atom.
How many moles in 190grams of calcium?
To calculate this you first have to find the molar mass of Calcium. Its the same as its atomic mass which is 40.08. You then divide the mass (190grams) by 40.08 which comes out to be 4.74 grams/per mole.
What do the molar masses of any two elements contain the same number of what?
Atoms have atomic weight not molar mass. Any atom-gram has 6,022 141 29(27)×1023 (this is the number of Avogadro) atoms.
