So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound

its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.

We just do a cross multiplication:
Answer:
$3584
Step-by-step explanation:

- one square foot is $16, so 224 sqaure feet are 224*16
= 3584
