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
