Problem 27P

Upon decomposition, one sample of magnesium fluoride produced 1.65 kg of magnesium and 2.57 kg of fluorine. A second sample produced 1.32 kg of magnesium. How much fluorine (in grams) did the second sample produce?

Step-by-Step Solution:
Step 1 of 3

Solution 27P

4.20 kg

Explanation:

You don't even need the balanced chemical equation for this one, all you need to use to solve this problem is the conservation of mass law.

So, the first sample produced 1.64 kg of magnesium and 2.56 kg of fluorine. Since the combined mass of the products must equal the mass of the reactant, you'll have

magnesium fluoride=1.64+2.56=4.20 kg

Out of this,

1.64 kg 4.20 kg⋅100%=39% by mass is magnesium, and

2.56 kg 4.20 kg⋅100%=61% by mass is fluorine.

Since the...
