What volume of a liquid having a density of 6.44 g/cm3 is needed to supply 9.00 grams of that liquid? Answer in cm3. I've tried to just plug in the known values to D=M/V and I'm not getting the right answer but I was told by a TA that by manipulating D=M/V to V=D/M I could get the answer. What I get is 6.44g/cm^3 / 9.00g, which comes out to .715555556 which with sif figs comes to .716 after rounding. Any thoughts?

I have been on prednisone for 2 weeks now 40 mg a day to help me get over pneumonia, my question is that since starting this medication I have put on 10 pounds (swelling) could this swelling be from prednisone, if so how long will it last. The weight cannot be from eating because I have not felt like eating. Just wondering if anyone knew. Thanks

Say you survive the initial enitial entry into the black hole. Have scientists found out instead of theorizing what actually goes on in a black hole? Is it just spinning you around? What would you see? Oh yeah, I always see pictures of black holes that show basically a stream of light shooting from end to the other with a disk in the middle. What would happen if you go through it? Would you just come out the other end?
