What is the atomic mass of a diamond?
As diamonds are almost pure carbon, the atomic mass would be carbon's atomic mass: 12.0107
What element was chosen as the standard foe defining the mole?
Carbon-12 was chosen as the standard for defining the mole because it has a precise atomic mass of 12 atomic mass units, making calculations easier for chemists to work with. This decision was made by the International Union of Pure and Applied Chemistry (IUPAC) in 1961.
What is molecular mass of pure gas?
The molecular mass of a pure gas is the sum of the atomic masses of all the atoms in its molecule. It is typically measured in atomic mass units (amu) or grams per mole (g/mol). The molecular mass is useful for calculating other properties of the gas, such as density or molar volume.
What is the atomic mass of copper and zinc?
The density of pure copper is: 8.94 g/cm^3 The density of pure zinc is: 7.13 g/cm^3
Is molar mass is mass in grams of one kilogram of any pure substance?
No, molar mass is the mass in grams of one mole of a substance. One mole is equal to the molecular weight of the substance in grams.
What is the atomic mass of a diamond?
As diamonds are almost pure carbon, the atomic mass would be carbon's atomic mass: 12.0107
What is the atomic mass for the element carbon is 12.011?
the atomic mass of just pure carbon would be twelve. the atomic mass is only effected by the number of protons and numbers of nuetrons
What are the molar mass of uranium 238?
Pure Uranium-238 has an Atomic Mass of 238.1252 amu. Thus one mole of it weighs 238.1252 grams.
How many moles are in 4.50g of carbon?
One mole of anything is Avagadro's constant, 6.02 × 1023. One mole of paperclips is 6.02 × 1023 paperclips, one mole of books is 6.02 × 1023 books, and one mole of carbon is 6.02 × 1023 atoms.
How much does carbon have?
Carbon has 6 protons, 6 electrons, and its most common isotope, carbon-12, has 6 neutrons. It has the electron configuration 1s2, 2s2, 2p2. Its atomic weight is about 12.01 grams per mole. It typically forms covalent bonds. Pure carbon can occur in two forms: the tip of a pencil and a diamond. (I'm not sure what you meant. If I didn't answer your question, post a message on my message board.)
What is the mass of one mole?
It depends on the substance. A mole is just a unit of amount, 6.02 × 1023. So that means that one mole of atoms is 6.02 × 1023 atoms; likewise, one mole of cars is 6.02 × 1023 cars and one mole of rice is 6.02 × 1023 grains. A mole of cars has a different mass than a mole of rice, so until you define what you're measuring, this question cannot be answered.
Why is atomic mass measured by relating it with the atomic mass of Carbon?
Atomic mass has always been a relative measure. Following Ostwald's recommendation, the relative atomic mass was based on Oxygen. However, in 1929, it was discovered that on this basis, the average mass of pure oxygen came out 0.0282% too high because of the heavier isotopes of oxygen.It was agreed in 1961 that the base be changed to carbon, but not just any isotope of carbon but specifically 12C.
What element was chosen as the standard foe defining the mole?
Carbon-12 was chosen as the standard for defining the mole because it has a precise atomic mass of 12 atomic mass units, making calculations easier for chemists to work with. This decision was made by the International Union of Pure and Applied Chemistry (IUPAC) in 1961.

How many moles are in 48g of carbon?
To determine this we must first know what the molar mass of Carbon is and that equals 12.01g. This mean for every 12.01g of Carbon, we have one mole. Therefore:48gC x (1 mole C/ 12.01g C) = 3.99 molesRounded off, in 48g of Carbon there are about 4 moles.
What is the mass in grams of 1.3 moles of silver?
There are 107.9 grams in one mole of pure silver. 107.9 a.m.u. is the average mass of isotopes of the element silver Answer to another (= not this one) question: The atomic number is the number of grams in a mole of any element. Hydrogen has an atomic number of 1 so a mole of hydrogen (okay, a half-mole of H2) weighs 1 gram. [ Silver is not Hydrogen ! and an atom is not a molecule]
What is the atomic mass for oxide?
It doesn't have an Atomic Mass, it is not an element (pure substance) it is a compound and therefore only has a molar mass.
