Question
How many significant figures are present in each of the following measured numbers?a. $1.01 \times 10^2$b. $1.00 \times 10^2$c. $6.6700 \times 10^8$d. $6.050 \times 10^{-3}$
Step 1
The general rules are: - All non-zero digits are significant. - Any zeros between significant digits are significant. - Leading zeros (zeros before the first non-zero digit) are not significant. - Trailing zeros in a decimal number are significant. Show more…
