<span>For question 1: we know the vA=10.0 cm3 and the m=89.6g. Using the equation D = m/vA give us: D = 89.6/10 = 8.96 g/cm3. Answer is (C) 8.96 g / cm3.
For question 2: We know the vA=1.2 cm3 and the D=.6 g/cm3. Using the equation D = m/vA and rearranging for m gives us m = D*vA: m = .6 * 1.2 = .72 g. Answer is (D) .72 g.
For question 3: We know the D = 8 g/cm3 and the m = 600g. Using equation D = m/vA and rearranging for vA gives us vA = m / D: vA = 600 / 8 = 75 cm3. Answer is (A) 75 cm3.</span>
