Answer:
Mass of oxygen = 54 gram
Explanation:
Given:
In a reaction:
Mass of carbon = 18 gram
Mass of carbon dioxide = 72 gram
Find:
Mass of oxygen needed = ?
Computation:
According to law of conservation of mass:
⇒ Sum of Mass of reactants = Sum of Mass of product
So,
⇒ 18 gram + Mass of oxygen = 72 gram
⇒ Mass of oxygen = 72 gram - 18 gram
⇒ Mass of oxygen = 54 gram
