Question

Calculate the volume in liters of a 7.76 g/dL iron(III) bromide solution that contains 427. g of iron(III) bromide (FeBr3).Round your answer to 3 significant digits.

Answer 1

5.50 L of solution

Procedure

We will use dimensional analysis to solve this question. After getting the answer, we will round to 3 significant digits. All the previous can be done in a single-step calculation.

`427\text{ g}\frac{1\text{ dL}}{7.76\text{ g}}\frac{1\text{ L}}{10\text{ dL}}=5.5026\approx5.50\text{ L}`
