6.21021 uranium atoms (1mole U/6.022 X 10^23)(238.0 grams/1 mole U)
= 2.45438 X 10^-21 grams of Uranium
Not too massive!
To find the number of uranium atoms in 6.2 g of pure uranium, you would first determine the molar mass of uranium, which is approximately 238.03 g/mol. Next, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the grams of uranium to number of atoms. So, 6.2 g of uranium would equal approximately 6.2 x (6.022 x 10^23 / 238.03) uranium atoms.
No, the number of atoms in a substance is determined by Avogadro's number (6.022 x 10^23 atoms/mol). To calculate the number of atoms, you need to convert the mass of each element to moles first using their respective molar masses, which are 22.99 g/mol for sodium and 238.03 g/mol for uranium.
9.6 grams of uranium (1 mole U/238.0 grams)(6.022 X 10^23/1 mole U) = 2.4 X 10^22 atoms 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 uranium atoms to grams, you need to know the molar mass of uranium. Uranium's molar mass is approximately 238.03 g/mol. Therefore, 7.5 x 10^21 uranium atoms would weigh approximately 0.625 grams.

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 find the grams of uranium oxide formed, we need to determine the molar mass of uranium and oxygen, calculate the moles of each element present, and finally the moles of uranium oxide formed. Then, we convert moles to grams using the molar mass of uranium oxide. The final answer for the grams of uranium oxide formed depends on the stoichiometry of the reaction.

Depends on the isotope. Most uranium found naturally is U238 and hence 238 g would be 1 mole. U235 used for fission and bombs would be 235g.
1 mole S atoms = 32.065 g S (atomic weight in grams) 1 mole S atoms = 6.022 x 1023 atoms S (Avogadro's number) Convert atoms to moles. 2.01 x 1022 atoms S x (1mol S/6.022 x 1023 atoms S) = 0.0334mol S Convert moles to mass in grams. 0.334mol S x (32.065g S/1mol S) = 10.7g S

To convert from grams to atoms, you need to use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the given amount of substance into moles and then multiply by Avogadro's number to get the number of atoms. To convert from mass (in grams) to the number of atoms, first find the molar mass of the substance, then divide the given mass by the molar mass to get moles, and finally multiply by Avogadro's number to obtain the number of atoms.
