A particular object weighs 313 N in air and 264 N when immersed in alcohol of density 0.70 g/cm3. What is the volume (in L) and the density (in kg/m3) of the object?
I had origionally used the 264N as the force of buoyancy and did the Fb=density*volume*g, then solved for volume.
Then, I used the 313N and used Fg=mg to solve for the mass and then divided that by the volume to get the density.
for some reason, It says I'm wrong, and maybe it was in my conversions and such.
could you please calculate so I can compare? would be greatly appreciated :)

the buoyancy force is the difference in the air weight and immersed weight
