An experiment calls for 10.0 mL of bromine (d = 3.12 g/mL). Since an accurate balance is available, it is decided to measure the bromine by mass. How many grams should be measured out? Multiple Choice 3.21 32.1 3.12 31.2 0.312

31.2g

Explanation:

The following data were obtained from the question:

Volume of bromine = 10mL

Density of bromine = 3.12 g/mL

Mass of bromine = ... ?

The Density of the substance is related to it's mass and volume by the following equation:

Density = Mass / volume

With the above equation, we can calculate the mass of bromine as follow:

Density = Mass / volume

Volume of bromine = 10mL

Density of bromine = 3.12 g/mL

Mass of bromine = ... ?

Density = Mass / volume

3.12 = Mass / 10

Cross multiply

Mass of bromine = 3.12 x 10

Mass of bromine = 31.2g

Therefore, the mass of bromine is 31.2g
