Answer : The total mass of oxygen gas released in the reaction will be, 12.8 grams
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of 
= Total mass of 
or,
Total mass of = Mass of 
+ Mass of 
As we are given :
Total mass of 
= 16.12 grams
The mass of 
= 9.72 grams
So,
Total mass of = Mass of + Mass of
Therefore, the total mass of oxygen gas released in the reaction will be, 12.8 grams
Answer:
[MCHM] = 7.52 M
Explanation:
This all about unit conversion
1 feet = 0.3048 meters
1 yard = 0.9144 meters
7.60 feet . 0.3048 = 2.31 meters deep
100 yd . 0.9144 meters = 91.44 meters long and 91.44 meters wide
In the river we have a volume of:
2.31 m . 91.44m . 91.44m = 19314.5 m³
1 dm³ = 1 L
1 dm³ = 0.001 m³
19314.5 m³ / 0.001 m³ = 19314542 L (The final volume of the river)
3.785 L = 1 gallon
In 19314542 L, we have (19314542 / 3.785) = 5102917 gallons
1 gallon = 128 oz
5102917 gallons . 128 = 653173376 oz
1 oz = 28.3495 g
653173376 oz . 28.495 = 1.86x10¹⁰ grams
Molar mass MCHM = 128 g/m
Moles of MCHM = 1.86x10¹⁰ grams / 128 g/m = 145312500 moles
Molarity = mol /L → 145312500 moles / 19314542 L = 7.52 M
