If the Atomic Mass of a carbon is 12 amu, 1 mole of pure carbon will have a mass of 12 g.
(that's the way an a.m.u. is defined: 1 a.m.u. = 1/12th of the mass of C-12 isotope atom)

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
How many moles 0.170g C?
The atomic mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 0.170/12.0 = 0.0142mol There are 0.0142 moles of carbon in a 0.170g pure sample.
Atomic mass trends in the periodic table?
Atomic Mass increases in size as the atomic number increases. For example, hydrogen weighs about 1.01 grams per mole and it has periodic #1. Helium is atomic #2 and it has an atomic mass of 4.00 g/mol. This trend continues all the way to the last known pure element.
How many moles of carbon does the Cullinan diamond contain?
621.35 grams is the mass given by wiki. So, since diamonds are mostly pure carbon............. 621.35 grams C (1 mole C/12.01 grams) = 51.736 moles of carbon
How many moles of silver are in 6.02 x 1023 atoms of silver?
http://en.wikipedia.org/wiki/Atomic_mass Conversion factor between atomic mass units and grams The standard scientific unit for dealing with atoms in macroscopic quantities is the mole (mol), which is defined arbitrarily as the amount of a substance with as many atoms or other units as there are in 12 grams of the carbon isotope C-12. The number of atoms in a mole is called Avogadro's number, the value of which is approximately 6.022 × 1023 mol-1. One mole of a substance always contains almost exactly the relative atomic mass or molar mass of that substance (which is the concept of molar mass), expressed in grams; however, this is almost never true for the atomic mass. For example, the standard atomic weight of iron is 55.847 g/mol, and therefore one mole of iron as commonly found on earth has a mass of 55.847 grams. The atomic mass of an 56Fe isotope is 55.935 u and one mole of 56Fe will in theory weigh 55.935g, but such amounts of pure 56Fe have never been found on Earth. The formulaic conversion between atomic mass and SI mass in grams for a single atom is: where u is the atomic mass unit and NA is Avogadro's number.
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.
What is the Molar mass for calcium oxide?
The molar mass of calcium oxide is 56.077 grams per mole
How many carbon atoms are in 2.6g of graphite pure carbon?
2.6 grams graphite ( just carbon ) (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 1.3 X 1023 atoms of carbon in that mass graphite ================================
How many moles 0.170g C?
The atomic mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 0.170/12.0 = 0.0142mol There are 0.0142 moles of carbon in a 0.170g pure sample.

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.
How many atoms of carbon are in a pure sample of carbon having a mass of 72.0 g?
72.0 grams Carbon (1 mole C/12.01 grams)(6.022 X 10^23/1 mole C) = 3.61 X 10^24 atoms of carbon
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]
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.
