586 g of Bromine (Br) occupies 188 mL. What is it's density?

Answer

To find the density of an object, you use the formula: Density = Mass / Volume. In this problem, the mass of Bromine is given as 586 grams (g) and the volume it occupies is given as 188 milliliters (mL). By substituting these values into the formula, we get: Density = 586 g / 188 mL. Performing the division gives a result of approximately 3.11702... g/mL. Looking at the significant figures, both the mass (586) and the volume (188) have three significant figures, so the answer should be rounded to three significant figures. Thus, the density is 3.12 g/mL. Comparing this to the given options, the correct choice is 3.12 g/mL.
