For adults, the rda of the amino acid lysine is 12 mg per kg of body weight. how many grams per day should a 75 kg adult receive? express your answer using two significant figures.

Respuesta :

1000mg = 1 gram 
So, hypothetically, if someone weighed 1kg, they would need 12mg of lysine daily. 
Then that means, a 72 kg adult would need 864mg of lysine daily, which is 0.864 grams.
