How many atoms of hydrogen are in 210 g of hydrogen peroxide (h2o2)?
Flauer [41]
Molar mass:

1 \ mol \ H_2O_2 = 34.0147 \ g \  H_2O_2

Grams to moles:

(210 \ g \ H_2O_2) * ( \frac{1 \ mol \  H_2O_2 }{34.0147 \ g \ H_2O_2}) = 6.17 \ mol \ H_2O_2

Moles to atoms (Avogadro's number):
1 \ mol = 6.022 * 10^{22} \ particles
(6.17 \ mol \ H_2O_2) *  (\frac{6.022 * 10^{22} \ molecules \ H_2O_2}{1 \ mol \ H_2O_2}) * ( \frac{2 \ atoms \ H}{molecule \ H_2O_2})

Answer:
= 7.43 * 10^{23} \ H \ atoms
