Best ResponseYou've already chosen the best response.2\[\sf \rho = \frac{m}{v}~~~~~~~~~~~~~~\rho = density \]\[\sf \rho = \frac{m_{obj}}{\Delta v}~~~~~~~~~\Delta v = change ~in~volume~of~water\]\[\sf \rho = \frac{7.5~g}{(30.1~ml ~~25.1~ml)}~ =~? ~~\frac{g}{mL}\]

Best ResponseYou've already chosen the best response.0The initial volume was 25.1mL and then the object of the mass which is 7.5g raised the final volume to 30.1mL. Looking for the density. Density =m/v. Mass given=7.5g. Water level before object submerged =25.1mL. Water level after submerged =30.2mL. Need density (g/mL). 30.1mL25.1mL=5mL. 7.5g/5mL= 1.5g/mL.
