Explanation:

Step1: Use the concentration formula

Concentration = $\frac{\text{Amount of substance}}{\text{Amount of solvent}}$
Here, the amount of substance (salt) is $140$ grams and the amount of solvent (water) is $12$ liters.
So, the formula becomes $\frac{140}{12}$.

Step2: Simplify the fraction

$\frac{140}{12}=\frac{35}{3}\approx11.67$ (divide numerator and denominator by $4$).

Answer:

$\frac{35}{3}\approx11.67$
