6 tons of pig ovaries were required to extract 13.0 mg of estrone. Assuming complete isolation of the hormones was achieved, calculate the mass percentage of estrone in the original tissue.
One US ton will be equal to 907.185 kg and 1kg will be equal to 10^6mg.
mass percentage of estrone= estrone mass/tissue mass * 100% mass percentage of estrone= 13mg/ (6 tons * 907.185 kg /ton * 10^6mg/kg) * 100% mass percentage of estrone=0.238 *[tex] 10^{-6} [/tex] %
