1 atomgram of a chemical element has 6,02214129(27)×1023 atoms.
1 atomgram=atomic weight of a chemical element exprimed in grams.
To convert grams to atoms, you need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, you need to determine the molar mass of the substance in grams/mol. Then, divide the given grams by the molar mass to get moles, and finally multiply by Avogadro's number to find the number of atoms.
To convert uranium atoms to grams, you need to know the molar mass of uranium. The molar mass of uranium is approximately 238.03 g/mol. First, calculate the moles of uranium atoms by dividing the number of atoms by Avogadro's number (6.022 x 10^23). Then, multiply the moles by the molar mass to get the grams of uranium.
To calculate the number of atoms in 3.4 grams of hydrogen peroxide, you first convert the grams to moles using the molar mass of hydrogen peroxide. Then, you use Avogadro's number to convert moles to atoms. There are approximately 6.022 x 10^23 atoms in 1 mole of a substance.
To convert grams to moles, you need to divide the given mass (2.9 grams) by the molar mass of the substance. The molar mass of a substance can be found by adding up the atomic masses of all the atoms in a molecule.

To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
(grams) x (6.02 x 10^23) / (mass number of specific element in grams)
Well, honey, to convert atoms to grams, you need to use the molar mass of copper. Copper has a molar mass of 63.55 g/mol. So, you multiply the number of atoms by the molar mass to get the mass in grams. In this case, it would be 2.11x10^24 atoms x 63.55 g/mol = your mass in grams. Easy peasy lemon squeezy!
To convert grams to atoms, you need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, you need to determine the molar mass of the substance in grams/mol. Then, divide the given grams by the molar mass to get moles, and finally multiply by Avogadro's number to find the number of atoms.
To convert 1.5 grams of carbon to the number of carbon atoms, you would need to use Avogadro's number, which is the number of atoms in one mole of a substance (6.022 x 10^23 atoms/mol), and the molar mass of carbon (12.01 g/mol). By dividing the given mass of carbon (1.5 g) by the molar mass of carbon, you can convert the grams to moles, and then use Avogadro's number to calculate the number of carbon atoms.
To convert uranium atoms to grams, you need to know the molar mass of uranium. The molar mass of uranium is approximately 238.03 g/mol. First, calculate the moles of uranium atoms by dividing the number of atoms by Avogadro's number (6.022 x 10^23). Then, multiply the moles by the molar mass to get the grams of uranium.
To convert grams to atoms, you need to first convert grams of nitrogen to moles using its molar mass (14.01 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, for 2.2 grams of nitrogen: Convert grams to moles: 2.2 g / 14.01 g/mol = 0.157 moles. Convert moles to atoms: 0.157 moles x 6.022 x 10^23 atoms/mol = 9.46 x 10^22 atoms of nitrogen.
To convert atoms of germanium to grams of germanium, you would need to multiply by the molar mass of germanium. The molar mass of germanium is approximately 72.63 grams per mole. This conversion factor allows you to go from the atomic scale to the macroscopic scale of grams. Simply multiply the number of atoms of germanium by 72.63 g/mol to obtain the mass in grams.
To calculate the mass of 19 atoms of copper in grams, you need to determine the molar mass of copper. The molar mass of copper is approximately 63.55 grams per mole. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to convert atoms to grams. So, the mass of 19 atoms of copper would be 19*(63.55/6.022e23) grams.
To find this, you need to first calculate the molar mass of gold (Au), which is 196.97 g/mol. Next, you convert the given mass (5 grams) to moles by dividing by the molar mass. Then, you use Avogadro's number (6.022 x 10^23) to convert moles to atoms. In this case, there are approximately 6.022 x 10^22 atoms in 5 grams of gold.
To calculate the number of atoms in 3.4 grams of hydrogen peroxide, you first convert the grams to moles using the molar mass of hydrogen peroxide. Then, you use Avogadro's number to convert moles to atoms. There are approximately 6.022 x 10^23 atoms in 1 mole of a substance.
