In a pretreatment facility, how many grams of ferrous chloride are in one liter of a solution containing 30 percent ferrous chloride with a density of 1.33 g/ml?

To find out how many grams of ferrous chloride are in one liter of a solution that contains 30 percent ferrous chloride with a density of 1.33 g/ml, we first need to understand what each term means.

The percentage concentration tells us the ratio of the solute (ferrous chloride) to the entire solution. A 30 percent solution means that there are 30 grams of ferrous chloride for every 100 grams of total solution.

Next, we need to calculate the total mass of one liter of this solution. One liter is equivalent to 1000 milliliters, and using the density of the solution, we can convert this volume into mass. Since the density provided is 1.33 g/ml, we multiply this by the volume in milliliters:

1000 ml x 1.33 g/ml = 1330 grams

Now, to find out how much of this mass is ferrous chloride, we apply the concentration percentage. Since 30 percent of the total mass of the solution is ferrous chloride, we calculate:

30% of 1330 grams = 0.30 x 1330 grams = 399 grams

Thus, in one liter of a 30 percent ferrous
