Answer:
The answer to your question is: 6 grams of hydrogen
Explanation:
Data
3.0 moles of hydrogen
1.5 moles of oxygen
3 moles of water
# of grams of hydrogen required to form 3 moles of water?
Equation
H₂ + 1/2 O₂ ⇒ H₂O
3 mole 1.5 moles 3 moles
Atomic weight of H₂ = 2 g
1 mole ----------------------- 2 g
3 moles --------------------- x
x = 3(2)/1 = 6 grams of hydrogens
