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

I am getting the wrong answer. Can you please check my work? My answer is off by a multiple of ten.

This is what I have so far. My answer is wrong, it is off by a multiple of 10

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

You have to divide the volume by 1000
