As Verne pointed out, nitro is probably the heaviest component in the mix.  To further confuse matters, some manufactures (few) mix the fuel by volume (ie 15% nitro means 15% by volume) where other manufactures mix by weight (ie 15% nitro means 15% of the weight is nitro).  Obviously, the ones that mix by volume have more nitro in their 15% fuel than the ones that mix by volume.
