Question

HELP!!1 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. PLEASE HELP!!!

(Im not sure if this helps but.... 3.1 g Br2= 1ml br2)

Answer 1

Answer:- 6200 kg

Solution:- Volume of bromine is given as
`2.0m^3` and it's density is
`(3.1g)/(mL)`. It asks to calculate the mass of bromine in kg.

We need to do the unit conversions for volume from
`m^3` to
`cm^3` and then mL. After this the volume is multiplied by density to get the mass in grams that could further be converted to kg. The set is shown as:

`2.0m^3(((100cm)^3)/(1m^3))((1mL)/(1cm^3))((3.1g)/(1mL))((0.001kg)/(1g))`

= 6200 kg

So, the mass of bromine in the given volume of it is 6200 kg.
