Answer
(a) $5pm = 5 \times 10^{-10} cm = 5 \times 10^{-3} nm$
(b) $8.5 cm^3 = 8.5 \times 10^{-6}m^3 = 8.5 \times 10^3mm^3$
(c) $65.2 mg$ $ = 6.52 \times 10^{-2}g = 6.52 \times 10^{10}pg$
Work Step by Step
We use unit conversions to find:
(a)
$5pm \times \frac{10^{-12}m}{1pm} = 5 \times 10^{-12}m$
$5 \times 10^{-12}m \times \frac{1cm}{10^{-2}m} = 5 \times 10^{-10}cm$
$5 \times 10^{-12}m \times \frac{1nm}{10^{-9}m} =5 \times 10^{-3}nm$
(b)
$8.5 cm^3 \times \frac{10^{-6}m^3}{1cm^3} = 8.5 \times 10^{-6}m^3$
$8.5 \times 10^{-6}m^3 \times \frac{1mm^3}{10^{-9}m^3} = 8.5 \times 10^3mm^3$
(c)
65.2 mg $\times \frac{10^{-3}g}{1mg} = 6.52 \times 10^{-2}g$
$6.52 \times 10^{-2}g \times \frac{1pg}{10^{-12}g} = 6.52 \times 10^{10}pg$
