The number of atoms of lead is 6,68.10e23.
how many atoms in 0.230 g pb
2(6.02 x 10^23) atoms
1.01 * 1^23
1.6 g C x 1 mol C/12 g x 6.02x10^23 atoms/mol = 8.1x10^22 atoms
8 g sulfur have 1,5027176187149.1023 atoms.
1.13 × 10 23 oxygen atoms
The number of atoms of lead is 6,68.10e23.
207.2/ 6.022*10^23 = 34.4 x 10-23 g, mass of 1 Pb atom For two atoms: 34.4*2= 68.8 x 10-23 g Pb 5.1*10^-23*4.003 g He (atomic mass) / 1 mol He= 20.4*10^-23 g He And the mass of lead is greater.
The answer is 3.32*10^23 atoms
Diamond is made of up carbon. So, it has a molar mass of 12 g/mol. 6 g/mol / 12 g = 0.5 mol 0.5 mol * 6x10^23 atoms/mol = 3x10^23 atoms There are 3x10^23 atoms in six grams of diamond.
2(6.02 x 10^23) atoms
1.01 * 1^23
23 g (6.02 x 1023 at / 4.00 g) = 3.5 x 1024atoms
1.6 g C x 1 mol C/12 g x 6.02x10^23 atoms/mol = 8.1x10^22 atoms
8 g sulfur have 1,5027176187149.1023 atoms.
2(6.02*10 23) atoms
16 g O x 1 mol/16 g = 1 mole and 1 mole = 6.02x10^23 atoms of O8g S x 1 mol/32 g = 0..25 moles S and then 0..25 moles x 6.02x10^23 atoms/mole = 1.5x10^23 atoms of S, or rounding to 1 significant figure, you have 2x10^23 atoms of S
