What two properties affect the density of ocean water? Chemistry Measurement Density 1 Answer anor277 Jan 9, 2017 #"Temperature and salinity."# Explanation: This link informs us that #rho_"seawater"=1.027*g*cm^-3#; #rho_"pure water"=1.000*g*cm^-3# (I changed the units so that they would be more accessible to chemists). And of course the density of water is affected by temperature to a lesser degree. Answer link Related questions How can density be used to identify substances? How can you find mass from density?
