what is the mass of chlorine used during the reaction? chlorine + potassium → potassium chloride ? 18.34 g 34.97 g give your answer to the correct number of significant figures.
Answer
Explanation:
Step1: Apply law of conservation of mass
According to the law of conservation of mass, the mass of reactants equals the mass of products. Let the mass of chlorine be $m$. So, $m + 18.34\ g=34.97\ g$.
Step2: Solve for the mass of chlorine
We can rewrite the equation as $m=34.97\ g - 18.34\ g$. $m = 16.63\ g$
Answer:
$16.63\ g$
