Final answer:
To make a 3000L of 5.00% sodium chloride solution, you would need 150,000g of NaCl. This is calculated using the mass percentage formula and assuming the density of the solution is similar to water.
Step-by-step explanation:
To calculate the mass of sodium chloride required for making a 3000L of a 5.00% sodium chloride solution, you need to know the mass percentage formula:
mass of the solute (NaCl) = (% concentration) × (total mass of the solution)
Assuming that the density of the solution is similar to that of water, which is approximately 1 g/mL, you can convert 3000L to grams, as there are 1000g in 1L:
3000L × 1000g/L = 3000000g of solution
Now, you can use the given 5.00% concentration to find out the mass of NaCl:
(5.00/100) × 3000000g = 150,000g of NaCl
This means you would need to weigh out 150,000g of NaCl and combine it with water to get the desired concentration of sodium chloride solution.
