Question
Calculate the volume in liters of a /67.8gdL iron(III) bromide solution that contains 99.0g of iron(III) bromide FeBr3.Round your answer to 3 significant digits.
Solution
To calculate the volume of the solution, we first need to understand the given information.
We know that the density of the solution is 67.8 g/dL, which means that there are 67.8 grams of the solution in every deciliter.
We also know that the solution contains 99.0 grams of iron(III) bromide.
-
Convert the density from g/dL to g/L because the volume is asked in liters. There are 10 deciliters in a liter, so we multiply the given density by 10: 67.8 g/dL * 10 = 678 g/L.
-
Now, we can find the volume by dividing the mass of the iron(III) bromide by the density of the solution. Volume = mass/density = 99.0 g / 678 g/L = 0.146 L.
So, the volume of the solution that contains 99.0 g of iron(III) bromide is approximately 0.146 liters.
