Answer:
308.78lb
Explanation:
Volume of water in the tank = 37gal
Density of water = 1.00g/mL
Unknown:
mass of water in the fish tank =?
Solution:
Density can be defined as the mass per unit volume of a substance. It is mathematically expressed as shown below:
Density = [tex]\frac{mass}{volume}[/tex]
Mass of water in the fish tank = density x volume
Now we have to convert the units into that which we can work with:
37gal to mL gives:
1 gal = 3785.41 ml
37 gal = 37 x 3785.41; 140060.17ml
mass of water = 1.00 g/mL x 140060.17ml = 140060.17g
Since our answer must be in pounds, we must convert grams to pounds:
1 grams = 0.00220462 pounds
140060.17g = 0.00220462 x 140060.17: 308.78lb
