the RDA of the amino acid lysine is 12 mg per kg of body weight. How many grams per day should a 77.0 kg adult receive?
math subject
you only have two pieces of information. How many ways can you use it? You want to convert kg of body weight to mg of medicine:
77kg * 12mg/kg = 924mg

To calculate how many grams per day a 77.0 kg adult should receive, we can use the Recommended Daily Allowance (RDA) of lysine.
The RDA tells us that the recommended amount of lysine is 12 mg per kg of body weight.
First, let's convert the adult's weight from kilograms to grams. Since there are 1000 grams in a kilogram, we can multiply 77.0 kg by 1000 to get 77,000 grams.
Now, we can calculate the lysine requirement by multiplying the body weight (in grams) by the RDA:
77,000 grams (weight) * 12 mg/kg = 924,000 mg of lysine
To convert from milligrams (mg) to grams (g), we divide by 1000:
924,000 mg / 1000 = 924 grams
Therefore, a 77.0 kg adult should receive approximately 924 grams of lysine per day.
