Take the actual sample weight of 13grams, and divide it by the atomic weight of chromium. This gives you your molar percentage of atoms. Now multiply this molar percentage by Avogadro's constant, the number of atoms in one mole, and this will give you your number of atoms in the sample.

How many moles of Cr are there in a sample of Cr that contains 4.37E 23 atoms?
To find the number of moles of Cr in the sample, first calculate the molar mass of Cr (chromium). Chromium has an atomic mass of approximately 51.996 g/mol. Next, divide the number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol) to convert atoms to moles. So, 4.37 x 10^23 atoms of Cr is equivalent to 0.725 moles of chromium.
How many grams would a sample of 3.01 x 1023 atoms of tellurium be?
To determine the number of grams in a sample of 3.01 x 10^23 atoms of tellurium, you would first convert the number of atoms into moles using Avogadro's number. Then, you would find the molar mass of tellurium and use it to convert moles into grams.

How many grams of silicon would there be in a sample that contained 9.99 x 1052 atoms?
To calculate the mass of silicon in the sample, you would first convert the number of atoms to moles using Avogadro's number. Then, you would calculate the mass of silicon in grams using the molar mass of silicon (28.0855 g/mol). The final mass would depend on the number of atoms in the sample.
If a sample of pure sodium has a mass of 8.2 grams and sodium has an average atomic mass of 22.99 gmol how many sodium atoms are there in the sample?
To calculate the number of sodium atoms in the sample, first find the number of moles in the sample by dividing the mass (8.2 g) by the molar mass of sodium (22.99 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Therefore, there are approximately 2.71 x 10^23 sodium atoms in a sample weighing 8.2 grams.

How many grams of silicon would there be in a sample that contained 9.991052 atoms?
1 mol of Si contains 6.02 x 1023 atoms (avogadro constant). Amount of Si = (9.99x1052) / (6.02x1023) = 3.75mol Molecular mass of Si is 28.1. Mass of Si = 3.75 x 28.1 = 105g
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
To determine the grams of silicon in the sample, you need to know the molar mass of silicon. Since silicon's atomic mass is approximately 28 g/mol, you can calculate the grams of silicon by dividing the number of atoms by Avogadro's number and then multiplying by silicon's molar mass. This calculation would provide you with the amount of silicon in grams in the given sample.
