100. Solving a chemistry problem

1% gelatin solution flows out of the viscometer within 29 seconds, and the same volume of water within 10 seconds, determine the relative viscosity of the gelatin solution, if its density is 1010 kg/m3, considering the density of water is 1000 kg/m3. The viscosity of water is ŋ20H2O=1.005* 10-3 n*s/m2.
