Code: Select all
print(f "How many moles are in 20 grams of H2O?")
float(grams_of_H_2_O) = 20
atomic_mass_of_H_2_O = 18.01528
moles_of_H_2_O = grams_of_H_2_O/atomic_mass_of_H_2_O
print(f "There are {moles_of_H_2_O} moles of H2O in 20 g of H2O")
\(\dfrac{1\,\,mol\,\,of\,\,pure\,\,substance}{atomic\,\,mass\,\,of\,\, pure\,\,substance}\)
\(20\,\,g\,\,H2O = \dfrac{mol\,\,H2O}{18.01528\,\,g\,\,H2O} =\)How many moles of H2O are in 20 g of H2O, given that the atomic mass of H2O is 18.01528 g?
