A backpacker carries 2.1 of white gas as fuel for her stove.How many pounds does the fuel add to her load? Assume the density of white gas to be 0.79 . Express your answer using two significant figures
You need to put dimensions with your numbers.
2.1 what? pounds? liters? kg? cups?
I assume the density you provided has dimensions of g/cm^3. You should have said so, or called it "specific gravity"
The white gas stove and fuel container also add to her load. They want you to ignore that.
