Answer:
36 g of water will produced.
Explanation:
Given data:
Mass of oxygen = 32 g
Mass of hydrogen = 4 g
Mass of water = ?
Solution:
First of all we will write the balance chemical equation.
2H₂ + O₂ → 2H₂O
Moles of oxygen = mass / molar mass
Moles of oxygen = 32 g/ 32 g/mol
Moles of oxygen = 1 mol
Moles of hydrogen = mass / molar mas
Moles of hydrogen = 4 g/ 2 g/mol
Moles of hydrogen = 2 mol
Now we compare the moles of water with oxygen and hydrogen.
O₂ : H₂O
1 : 2
H₂ : H₂O
2 : 2
The moles of water produce by hydrogen and oxygen are same.
Mass = moles × molar mass
Mass = 2 mol × 18 g/mol = 36 g
