What are we trying to match the units of density with?

another quick question when we plugin values for density for water do we use 1.0 or 1000

the question is: a submarine with volume(total) 4.67x10^3 and mass of 4.39x10^6 is floating at the surface of sea water, of density 1.03x10^3 a) what is the buoyant force on the submarine? ------------ In this case, we do not have enough information to use the equation...

Then why do we need to use the formula: F(b) = (rho) (V) (9.8) to find the buoyancy force when we could just multiply its mass by 9.8 ??

Hi, i have a quick question regarding the above subject. If F(b) = (rho) (V) (9.8) and F(b) = F(g) and F(g) = (m) (9.8) then wouldn't F(b) = (m) (9.8) ?
