Question

Which of the following has the greatest density?

1 ft3 of Lead weighing 700 pounds

2 ft3 of Iron weighing 980 pounds

30 liters of Acetone weighing 23.73 kg

1 m3 of Toluene weighing 866 kg

Thanks

Answer 1

the lead its density is 700lbs/ft^3

Answer 2

i havent learnt this before but you obviously have to convert these substances to a common base then multiply each ones mass by its volume (because that is the definition of density). I would assume that you would take each one's molar mass and multply it by its volume. Sorry for not giving a complete answer.. i do not have the knowledge to answer this question fully

Answer 3

1.) 700 pounds/ft3

2.) 490 pounds/ft3

3.) 49.38 pounds/ft3 (I used conversion)

4.) 54.06 pounds/ft3

1 ft3 of Lead weighing 700 pounds has the greatest density.
