Final answer:
The volume of 10.5 g of bromine (Br2) is approximately 3.365 mL, calculated by dividing the mass by the density of bromine, which is 3.12 g/mL.
Step-by-step explanation:
To calculate the volume in mL of 10.5 g of Br, we first need to specify the substance we are talking about since Br is the chemical symbol for bromine, but it usually exists as diatomic Br2 in nature. Assuming we are dealing with liquid bromine (Br2), we need to know its density to find the volume. The density of bromine (Br2) is around 3.12 g/mL at room temperature. Using the formula:
Volume = mass / density
The volume of 10.5 g of Br2 would be calculated as follows:
Volume = 10.5 g / 3.12 g/mL = 3.365 mL
Therefore, 10.5 g of bromine (Br2) would have a volume of approximately 3.365 mL.
