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)
There are approximately 6.022 x 10^22 atoms in 1 gram of sulfur based on Avogadro's number, which is the number of atoms or molecules in one mole of a substance.
There are 6.02 x 10^23 atoms of calcium in 1 gram of calcium.
There are 10 decigrams in one gram.
there a 1000 milligrams in 1 gram
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!

There are approximately 6.022 x 10^23 sulfur atoms in one gram of sulfur, according to Avogadro's number which represents one mole of atoms.
There are approximately 6.022 x 10^22 atoms in 1 gram of sulfur based on Avogadro's number, which is the number of atoms or molecules in one mole of a substance.
It depends on the atomic mass of a substance. To find out, divide the 1 by the atomic mass of the element (found on the periodic table), then multiply by 6.02*1023. Ag=(1/Am)*6.02*1023 Where Am=atomic mass of the element, and Ag=the number of atoms in a gram.
A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
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

It's much simpler than you're probably thinking. You use the term gram atomic weight for atoms, and the term gram molecular weight for molecules. That's all. The gram molecular weight of a molecule is the sum of the gram atomic weights of the atoms making up that molecule.
For the isotope plutonium-239: cca. 2,52.1021atoms.
