-If the density of a substance is $5.21 \times 10 ^ { - 4 }$ tons per cubic foot, what would be the mass of $8.51 \times 10 ^ { - 3 }$ cubic feet of this substance. (Use the formula $D = \frac { M } { V }$ and round to the nearest hundredth, if necessary.)
A) $4.43 \times 10 ^ { - 7 }$ tons
B) $4.43 \times 10 ^ { - 6 }$ tons
C) $0.44 \times 10 ^ { - 6 }$ tons
D) $4.43 \times 10 ^ { - 5 }$ tons

To find the mass (M) of the substance, rearrange the formula to $M = D \times V$. Substituting the given values, $M = 5.21 \times 10^{-4} \times 8.51 \times 10^{-3}$. Multiplying these gives $M = 4.43 \times 10^{-6}$ tons.
