Answer

Explanation:

Step1: Convert Tg to g

We know that $1\ Tg = 10^{12}\ g$. So for $9.900\times 10^{-6}\ Tg$, we have $9.900\times 10^{-6}\times10^{12}\ g=9.900\times 10^{6}\ g$. The intermediate - answer numerically is $9.900\times 10^{6}$ and the units are $g$.

Step2: Convert g to Mg

We know that $1\ Mg = 10^{6}\ g$. So, $\frac{9.900\times 10^{6}\ g}{10^{6}\ g/Mg}=9.900\times 10^{0}\ Mg$. The final answer numerically is $9.900\times 10^{0}$ and the units are $Mg$.

Answer:

  1. B. $9.900\times 10^{6}$
  2. J. g
  3. E. $9.900\times 10^{0}$
  4. K. Mg
