Solution:
Given data:
- Percentage of NaCl in brine solution = 3.87%
- Density of brine solution = 1.036 g/mL
- Mass of NaCl required = 0.32 g
Step 1: Calculation of mass of brine solution required
Let's assume that we need to evaporate 'x' mL of brine solution to obtain 0.32 g of NaCl.
- Mass of brine solution required = Volume of brine solution x Density of brine solution
- Mass of NaCl in the solution = Percentage of NaCl x Mass of brine solution
- Therefore, Mass of NaCl in 'x' mL of brine solution = (3.87/100) x (x x 1.036)
- Equating the mass of NaCl in the solution with the required mass of NaCl, we get:
(3.87/100) x (x x 1.036) = 0.32
x = 8.04 mL
Step 2: Calculation of volume of brine solution to be evaporated
As we have assumed that we need to evaporate 'x' mL of brine solution to obtain 0.32 g of NaCl, substituting the value of 'x' in the above equation, we get:
- Volume of brine solution to be evaporated = 8.04 mL - x = 8.04 - 8 = 0.04 mL
Therefore, we need to evaporate 0.04 mL of brine solution to obtain 0.32 g of NaCl.
Hence, the integer value obtained after solving the above problem is 8.
Given data:
- Percentage of NaCl in brine solution = 3.87%
- Density of brine solution = 1.036 g/mL
- Mass of NaCl required = 0.32 g
Step 1: Calculation of mass of brine solution required
Let's assume that we need to evaporate 'x' mL of brine solution to obtain 0.32 g of NaCl.
- Mass of brine solution required = Volume of brine solution x Density of brine solution
- Mass of NaCl in the solution = Percentage of NaCl x Mass of brine solution
- Therefore, Mass of NaCl in 'x' mL of brine solution = (3.87/100) x (x x 1.036)
- Equating the mass of NaCl in the solution with the required mass of NaCl, we get:
(3.87/100) x (x x 1.036) = 0.32
x = 8.04 mL

As we have assumed that we need to evaporate 'x' mL of brine solution to obtain 0.32 g of NaCl, substituting the value of 'x' in the above equation, we get:
- Volume of brine solution to be evaporated = 8.04 mL - x = 8.04 - 8 = 0.04 mL
Therefore, we need to evaporate 0.04 mL of brine solution to obtain 0.32 g of NaCl.
Hence, the integer value obtained after solving the above problem is 8.
