1. (2×103g +7.613g)/(0.069cm3 - 0.033cm3) Carryout that operation as if it was the calculation of experimental result, and Express the answer in the correct unit and the correct number of significant figures.

Please don't provide handwritten solution .....

How do I solve the following problem with the proper number of significant figures? Mainly parts E and F.

That wasn't the answer im afraid.

Carbon monoxide(CO) is a poisonous gas because it binds..... calculate the volume in the listers occupied by a carbon monoxide in a room that measures 19.11m long, 11.71 m wide, 16.09 m high at this concentration. Be sure your answer has the correct number of significant digits.  Volume of CO in the room:    L
