Final answer:
Each person's body contains 2 * 10^2 grams of sodium chloride, so for 1.8*10^3 people, you multiply these two numbers together to get 360 * 10^5 grams. This can then be expressed in scientific notation as 3.6 * 10^5 grams, making the correct answer A) 3.6 * 10^5.
Step-by-step explanation:
To determine how much sodium chloride is contained in the bodies of 1.8*10^3 people with each weighing 50 kilograms, you would start by multiplying the sodium chloride content of one person's body by the number of people. Given that one person's body contains 2 * 10^2 grams of sodium chloride, you multiply this amount by 1.8*10^3 to find the total sodium chloride content for all of the people combined.
Mathematically, this calculation is: 2 * 10^2 grams/person × 1.8 * 10^3 people = 360 * 10^5 grams of NaCl
To represent this number in scientific notation, you can rewrite it as 3.6 * 10^5 grams of NaCl, which represents the sodium chloride content for the group of people. By converting to scientific notation, we have consolidated the answer to a more convenient form. Therefore, the correct answer to the question is A) 3.6 * 10^5.
