The mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.
<h3>
How do you calculate the mass of sodium chloride required?</h3>
Given that weigh of the person is 50 KG. The mass of the sodium chloride in one person is given below.
![1 \;\rm Person = 2\times 10^2\;\rm g](https://tex.z-dn.net/?f=1%20%5C%3B%5Crm%20Person%20%3D%202%5Ctimes%2010%5E2%5C%3B%5Crm%20g)
The mass of sodium chloride is calculated as given below.
![1.8\times 10^3 \;\rm Person = 2\times 10^2 \times 1.8\times 10^3](https://tex.z-dn.net/?f=1.8%5Ctimes%2010%5E3%20%5C%3B%5Crm%20Person%20%3D%202%5Ctimes%2010%5E2%20%5Ctimes%201.8%5Ctimes%2010%5E3)
![1.8\times 10^3 \;\rm Person = 3.6\times 10^5\;\rm g](https://tex.z-dn.net/?f=1.8%5Ctimes%2010%5E3%20%5C%3B%5Crm%20Person%20%3D%203.6%5Ctimes%2010%5E5%5C%3B%5Crm%20g)
Hence we can conclude that the mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.
