# Physics Help!!! How many atoms of hydrogen are in 250g [Solved]

which means 34.0138 grams is 6.023*10^23 molecules

Discover molecular weight of H2O2: 2(1.01) 2(16.0) = 34.02 g/mole
Discover variety of moles in 250 g: (250 g)(1 mole/34.02 g) = 7.3486 moles
Variety of hydrogen atoms = (2)(7.3486 moles) = 14.6972 moles H atoms
Quantity atoms = (14.6972 moles)(6.022 x 10^23 atoms/mole) = 8.851 x 10^24 atoms

H = 1.0079 g /mol
O = 15.999 g/mol

so 250g/34.0138 = 7.35 mols

so the variety of molecules
= 6.023*10^23 * 7.35
= 4426905000000000000000000
= 4.427 *10^24 molecules of hydrogen peroxide

so the variety of molecules
= 6.023*10^23 * 7.35
= 4426905000000000000000000
= 4.427 *10^24 molecules of hydrogen peroxide

so the variety of molecules
= 6.023*10^23 * 7.35
= 4426905000000000000000000
= 4.427 *10^24 molecules of hydrogen peroxide

good luck hope that helps

variety of atoms of H in 250 grams H2O2 is
n = 8.854*10^24

good luck hope that helps

good luck hope that helps
