The mass is 1,62.10e-11.
dose 23 grams of sodium and 238 grams of uranium have equal number of atoms in them
Not much! 2980 atoms sodium [1 mole Na/6.022 X 1023 (atoms)][22.99 grams/1 mole Na] = 1.138 X 10 -19 grams sodium ====================
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
# of moles = Mass÷ Formula weight Example: 6 grams of Carbon atoms Carbon has an atomic mass of 12 grams so according to the Equation # of moles = 6÷ 12 = 0.5 moles For a compound such as CO2 , Formula weight = ( 1 mole of carbon atom weighs 12 grams + 2 moles of oxygen atoms weighs 32 grams ) 44 grams. Example: 24 grams of carbon dioxide = 24÷ 44 = 0.5454 moles So for sodium, # of moles = 45.48 g ÷ 22.99g/mole = moles You divide!
Sodium phosphate is Na3PO4, which means each molecule of sodium phosphate is four atoms of oxygen bound to a central phosphorus atom, with three sodium atoms arranging themselves randomly to three of the oxygen atoms.

1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
Sodium has an atomic mass of 29.990 g/mol. This means that 124 sodium atoms have a mass of 3718.76 amu, if the isotopes follow the average. To find in grams, the following must be used: 124 sodium atoms equal 2.0598 * 10-22 moles, so 124 sodium atoms have a mass of 6.177 *10-21 grams.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
