A sample of vermilion colored mineral was weighed in air, and then weighed again while suspended in water. An object is buoyed up by the mass of fluid displaced by the object. In the air mineral weighed 18.49 g; in water it weighed 16.21 g. the density of air and water are 1.205 g/L, 0.9982 g/cm2 respectively. What is the density of the mineral?

density=d,volume=v, mass=vd,

vd-(v*0.001205)=18.49

vd-(v*0.9982)=16.21

solve the above two equations for d
