How many atoms are there in 2.50 mol of hydrogen?

Answer 1

For this problem you don't need the Atomic Mass of the element. If you want to convert moles to atoms, you need to take the number of moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for units to cancel.

2.50 moles H × (6.02 × 1023 atoms) = 1.51 ×1024 atoms H

Answer 2

If you mean in 2.5 moles of the element H, then it will be 2.5 moles H x 6.02x10^23 atoms/mole = 1.5x10^24 atoms. If you mean 2.50 moles of hydrogen gas (H2), then it will be twice that or 3x10^24 atoms.

Answer 3

2.5 mol of uranium = 2,5 x Avogadro's number = 15,055354475.1023 atoms

Answer 4

1 mole atoms U = 6.022 x 1023 atoms

2.50mol U x 6.022 x 1023 atoms/1mol = 1.51 x 1024 atoms U

Answer 5

2.50 mole of H2 contains 5.0 moles of hydrogen atoms (H),

which are 5.0 * 6.02*10+23 atoms (particles) = 3.0*1024 atoms H

Answer 6

2.5 moles × (6.02 × 1023) = 1.51 × 1024 atoms

Answer 7

15,055354475.1023 uranium atoms

Answer 8

If 2,5 is grams: 6,325.1021 atoms.
