Answer

Explanation:

Step1: Determine uncertainty of first number

The number $5.55555\times 10^{5}\ \mu g$ has the last - significant digit in the hundred - thousandths place of the coefficient. The uncertainty is $\pm0.00001\times 10^{5}\ \mu g$.

Step2: Determine uncertainty of second number

The number $5.55\times 10^{5}\ \mu g$ has the last - significant digit in the hundredths place of the coefficient. The uncertainty is $\pm0.01\times 10^{5}\ \mu g$.

Answer:

  1. A. $+/- 0.00001\times 10^{5}\ \mu g$
  2. C. $+/- 0.01\times 10^{5}\ \mu g$
