A square yard is 9 square feet (3x3) 11x16=176 square feet 176 divided by 9 = 19.55 square yards
If your tiles are really 25 square feet, you will need 7 of them to cover that area. Might as well get 8 to be safe. I don't know how many are in a box.
Take the 11 as 1 + 10 then11 x 16 is 1 x 16 = 16 and 10 x 16 = 160 then 16 + 160 = 176

11*16*2.5 = 440 cubic feet. 440 cubic foot = 2 740.687 602 gallon [UK] 440 cubic foot = 3 291.428 571 4 gallon [US, liquid]
At our water garden center, Aquatic Connections, the two most popular pond sizes are 8ftx11ft and 11ftx16ft. If the average depth is 2 feet, that would mean the gallons of water would be roughly 1300-1500 gallons for the 8x11 and 2000-2500 gallons for the 11x16. The difference would depend on the amount of rock in the bottom of the pond.
The molar mass of sucrose is 342.3 g/mol. First, convert grams of sucrose to moles. 125g / 342.3 g/mol = 0.365 moles of sucrose. Then, calculate molarity as moles of solute per liter of solution. Molarity = 0.365 moles / 3.50 L = 0.104 M.
n = amount of mole
