0.188 moles Na (6.022 X 10^23/1 mole Na)
= 1.13 X 10^23 atoms of sodium
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
1.8 moles
1.56 X 10^21 atoms of sodium ( 1 mole Na/6.022 X 10^23) = 0.00259 moles sodium or 2.59 X 10^-3 moles sodium
32.7 g x 1 mol/22.99 g = 1.422 mol x 6.022x10^23 molecules/1mol = 8.565 x 10^23 molecules(also called atoms)
0.013089701
0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms
Atomic Mass of Na: 23.0 grams1.50 moles × (6.02 × 1023 atoms) = 9.03 × 1023atoms
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
In a mole there is 6.022 x 1023 atoms. In two moles there are twice that amount.
The answer is NA x 3,5 = 21,0775.10e+23.
I assume you mean 10.453x1023 atoms of sodium. 1 mole of anything contains 6.02x1023 representative particles (Avogadro's number), so if you divide the given number of atoms by Avogadro, you get 1.736 moles.
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
How many atoms of gallium are in 2.85 x 103 g of gallium?
One mole is 6.02*1023 atoms. So to find out how many moles are in 1.43*1024 , it's as simple as dividing the second number by the first. This results in 2.38 moles (rounded to significant figures)
0.25 x 6.022 x 10^23=1.05055 x10^23
1.8 moles
