Answer:
2370.0 contains 4 significant digits and Option (c) is correct .
\(1.20\times 10^{-3}\ contains\ three\ significant\ digit.\)
Option (b) is correct .
Step-by-step explanation:
Rules for finding significant digit .
1 : Non-zero digits are always significant.
2: Any zeros between two significant digits are significant .
3: Trailing zeros in the decimal number is also significant.
As the number given be 2,370.0.
\(= \frac{23700}{10}\)
Simplify the above
= 2370
Thus by using the rule given above.
2370.0 contains 4 significant digits.
Option (c) is correct .
As the number given be 0.00120 .
\(= \frac{120}{100000}\)
Simplify the above
\(= \frac{1.20}{1000}\)
\(= 1.20\times 10^{-3}\)
Thus by using the rule given above.
\(1.20\times 10^{-3}\ contains\ three\ significant\ digit.\)
Option (b) is correct .
