Homework Help: chem/plz/check work studying for a final

Posted by julia on Thursday, December 16, 2010 at 11:58am.

A 20.5 lb cast iron boat anchor displaces 1.33 qt of water when submerged. What is the density of the cast iron, in g/cm3?

1L=1.057 qt
1kg=2.205lb
1lb=453.6g

20.5lb X 453.6g/ 1lb = 9298.9g

1.33qt X 1L/1.057qt = 1.26L

1.26L X 1000cm3/1L = 1260cm3

9298.9g/1260cm3 = 7.38g/cm3

**now why my teacher answer is 7.39g/cm3???
