1 mole Na = 6.022 x 1023 atoms Na 0.200 mole Na x (6.022 x 1023 atoms/1 mole Na) = 1.20 x 1023 atoms Na
How many atoms of gallium are in 2.85 x 103 g of gallium?
1, because Na does not have a number after it.
1mol Na in grams = 22.989770g 1mol Na atoms = 6.022 x 1023 atoms 1 x 1020 atoms Na x 1mol/6.022 x 1023 atoms x 22.989770g/mol = 0.004g Na (rounded to one significant figure)
NaCl is one atom of Na and one atom of Cl. Therefore, each molecule of NaCl has 2 atoms each, combined.
6 Na means 6 atoms of Sodium 6 Na means 6 atoms of Sodium
1 mole Na = 6.022 x 1023 atoms Na 0.200 mole Na x (6.022 x 1023 atoms/1 mole Na) = 1.20 x 1023 atoms Na
6 atoms only
6.22 x 1023 atoms
1, because Na does not have a number after it.
0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms
0.013089701
1 mole = 6.022 x 1023 4.8mol Na x (6.022 x 1023 atoms Na/mol Na) = 2.9 x 1024 atoms Na
3.5 grams Na (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na) = 9.2 X 1022 atoms of sodium ===================
How many atoms of gallium are in 2.85 x 103 g of gallium?
0.188 moles Na (6.022 X 10^23/1 mole Na) = 1.13 X 10^23 atoms of sodium
Two atoms in the formula unit (not molecule): Na and Cl.
