To solve this, you are first going to use the given conversion of 1.00 pounds to grams (454g). Make sure that the equation they give you in the book is balanced (if not balance it). Then, you will want to convert the grams of the fat to moles by using the molar mass of the fat. Once you do this you can convert from moles of one fat to the moles of oxygen by using your balanced equation. Then, convert the O2 to grams to find the mass needed.
