about 99% of the mass of the human body is made up of just six elements.
Find the mass of each element in a human body iwth mass 60kg.
could you please explain to me how to do this? your help is appreciated.:)
60 kg. * 0.99 =59.4 kg
0.65 * 59.4 = 38.61 kg
0.18 * 59.4 = 10.69 kg
I'm sure you can finish the rest of these calculations.
