To balance this equation simply place the coefficient 2 in front of both the iron metal and the iron II oxide FeO.
2.25739773716275. I used a calculator during class today to get this answer, and I am pretty sure it is right, hope it helps.
Recall that 1 gallon = 3.785 L, and 1 L = 1000 mL, so to calculate volume in millilitres, multiply by 3.785 and 1000, resulting in 3785 mL. Next, multiply volume by density to calculate mass (Density = Mass/Volume), so 3785 mL * 1.000 g / mL = 3785 g of water.
