A sample of an unknown material appears to weigh 295 N in air and 165 N when immersed in alcohol of specific gravity 0.700.

(a) What is the volume of the material?

___________m^3

(b) What is the density of the material?

____________ kg/m3

295N-165N=130N

F=pVg

130N=(.700)V(9.8m/s^2)

V=18.93

F=mg

295N=m(9.8)

m=30.10kg

pV=m

p(18.93)=30.10

p=1.59kg/m^3
