Ml is equal to 1 cm^3. what is the mass (in kg) of 2.0m^3 of br2? hint: you will have to make a new conversion factor between cm^3 and m^3. this can be done by cubing both sides of the 100 cm= 1m conversion factor. you must remember to cube the number as well as the units. ! (im not sure if this 3.1 g br2= 1ml br2)
