Answer
a) $10^{9}$ kg
b) 6.5 $\times 10^{23}$ nm
c) 2.5 $\times 10^{-17}$ kg
d) 8.0 liters
e) $10^{3}$ microliters
f) $10^{6}$ picograms
Work Step by Step
a) 1 teragram = $10^{9}$ kg
b) 1 terameter = $10^{21}$ nm
Thus, 650 termameter = 6.5 $\times 10^{23}$ nm
c) 1 femtogram = $10^{-18}$ kg
Thus, 25 femtogram = 2.5 $\times 10^{-17}$ kg
d) 1 cubic decimeter = 1 liter
Thus 8.0 cubic decimeter = 8.0 liters
e) 1 ml = $10^{3}$ microliters
f) 1 microgram = $10^{6}$ picograms
