A gallon of water and a gallon of antifreeze solution weigh respectively 8.4 and 9.2 lb . The antifreeze solution has a relative density of (a)0.095 (b)0.80 (c)0.91 (d)1.1 Share with your friends Share 3 Pragati Singh answered this (C) -3 View Full Answer Avnish Gawande answered this Relative density = mass of substance/mass of equal volume of water So. RD 9.2/8.4=1.09. So approx=(d)1.1 2 Chari answered this A gallon And gallon of antifreeze solution V respectively 8.4 and 9.2 lb the antifreeze solution as a relative density of 0 Chari answered this A gallon of water and gallon of antifreeze solution V respectively 8.4 and 9.2 lb the antifreeze solution as a relative density of 0
