To find the number of atoms in a gram you must have the identity of the substance (the molar mass) and solve for the number of moles in 1 gram
moles= 1gram / molar mass of substance
# atoms = (moles)(Avogadro's number)

∙ 12y agoOne gram of 56Fe would contain the molar number divided by either 55.847 or 55.935 (the atomic weight). This would be 1.078 x 1022 atoms or 1.076 x 1022 atoms.

∙ 11y ago1 mole Mg = 6.022 x 1023 atoms
1 mole Mg = 24.3050g (atomic weight in grams)
1g Mg x (1mol/24.3050g) x (6.022 x 1023atoms/mol) = 2 x 1023 atoms (rounded to 1 significant figure)

If you could count at the rate of 3 atoms per second how long would it take to count the atoms in 1 gram of Copper?
Wiki Answer to "http://wiki.answers.com/Q/If_you_could_count_at_the_rate_of_3_atoms_per_second_how_long_would_it_take_to_count_the_atoms_in_1_gram_of_Copper"Every substance on earth has an atomic or molecular weight. If one weighs out the atomic or molecular weight of a substance in grams it is called one gram molecular weight commonly called one gram mol. One gram mol of any substance contains 6.0221367 × 1023 atoms which in scientific notation is generally expressed as 6.02E23 atoms of that substance, E meaning the exponent on the number 10. This number is named Avogadro's constant after Amedeo Avogadro, an Italian scientist who first identified this quantity in 1811. 6.02E23 means 6.02 with the decimal point moved to the right 23 times! So the number is 602,000,000,000,000,000,000,000 atoms in one gram mol of any substance. The atomic weight of hydrogen, the lightest substance, equals 1.0079. So, 1.0079 grams of hydrogen is one gram mol and it contains 6.02E23 atoms of hydrogen. The atomic weight of copper is 63.546. If one weighs out 63.546 grams of copper, that pile is one gram mol of copper and it also contains 6.03E23 atoms of copper. So, only 1 gram of hydrogen contains the same number of atoms as 63.5 grams of copper! The question is about the time required to count the atoms in only one gram of copper at a rate of 3 atoms per second. One gram of copper would contain many less atoms than one gram mol (63.546 grams). That one gram would contain only 1/63.546 or 0.0157 gram mol of copper. So, multiply 0.0157 gram mol by 6.02E23 and the one gram would contain only 9.47E21 atoms of copper. To count the atoms, divide by 3 atoms per second; then divide by 60 seconds per minute; then divide by 60 minutes per hour; then divide by 24 hours per day; then divide by 365 days per year; then divide by 1000 years per millennium. The answer is that the calculation procedure will take1.00E11 millennia to count the atoms at 3 atoms per second or 1E14 years. That's one hundred trillion years . . . and that with no sleep and no food or water to interrupt the counting! Or, if you could count 100 billion atoms per second, you could finish in slightly less than 17 minutes! A person undertaking this project should at least consider his or her limitations!

How many atoms are in 1g of sodium lithium and chlorine?
By definition, every gram atomic mass of an element contains Avogadro's Number of atoms. The grams atomic masses of the three elements in the question are: sodium, 22.9898; lithium, 6.941; and chlorine, 35.453. Therefore, one gram of sodium contains (6.022 X 1023)/22.9898 or about 2.619 X 1022 atoms; one gram of lithium contains (6.022 X 1023)/6.941 or about 8.676 X 1022 atoms; and one gram of chlorine contains (6.022 X 1023)/3.5453 or about 2.619 X 1022 atoms. (If the specified "1g" is considered possibly inexact, each value should be rounded to only one significant digit, because no more are justified.)
How many moles of nickel (Ni) atoms are in 125 g Ni?
There are 58.6934 gram in one mole of Ni atoms, so there are125(g Ni) / 58.6934 (g.mol-1 Ni) = 2.13 moles in 125 gram Ni

How many atoms are in exactly 6 gram of carbon - 12 have?
One half of Avogadro's number, or about 3.011 X 1023.
How many atoms are in one gram of calcium?
To work this out you need to know the atomic weight of calcium and Avogadros number, which is the number of atoms in a gram atom. Calcium has an atomic weight of 40.078. Therefore a gram ato is 40.078 grams which contains 6.02214129(27)×1023 atoms. 1g of calcium contains 6.02214129(27)×1023 / 40.078 1.502 X 1022
