#rho~=4*g*L^-1#

Explanation:

#"Density, "rho="Mass"/"Volume"# #=# #(0.934*g)/(0.250*L)# #=# #??g*L^-1#.

Relative density relies on a reference substance, typically water.
#"Relative Density"=rho_"substance"/rho_"water"#, i.e. this is a dimensionless quantity. And #rho_"water"# #=# #1.0*g*mL^-1# under most circumstances.
