Answer :
To determine the amount of sodium chloride needed to make 19 liters of a solution with a concentration of 3.2 grams per liter, we need to use the formula for calculating the total mass of solute in the solution. The formula is:
[tex]\[ \text{Mass of solute} = \text{Volume of solution} \times \text{Concentration of solute} \][/tex]
Given the following values:
- The volume of the solution = 19 liters
- The concentration of sodium chloride = 3.2 grams per liter
We plug these values into the formula:
[tex]\[ \text{Mass of sodium chloride} = 19 \, \text{L} \times 3.2 \, \text{g/L} \][/tex]
By multiplying these together:
[tex]\[ \text{Mass of sodium chloride} = 60.8 \, \text{g} \][/tex]
Hence, to make 19 liters of the solution with a concentration of 3.2 grams of sodium chloride per liter, you need 60.8 grams of sodium chloride.
[tex]\[ \text{Mass of solute} = \text{Volume of solution} \times \text{Concentration of solute} \][/tex]
Given the following values:
- The volume of the solution = 19 liters
- The concentration of sodium chloride = 3.2 grams per liter
We plug these values into the formula:
[tex]\[ \text{Mass of sodium chloride} = 19 \, \text{L} \times 3.2 \, \text{g/L} \][/tex]
By multiplying these together:
[tex]\[ \text{Mass of sodium chloride} = 60.8 \, \text{g} \][/tex]
Hence, to make 19 liters of the solution with a concentration of 3.2 grams of sodium chloride per liter, you need 60.8 grams of sodium chloride.
