The number of significant figures in \(3.78 \times 10^{22} \mathrm{~kg}\) is
- A \(19\)
- B \(25\)
- C \(3\)
- D \(22\)
Answer & Solution
Correct Answer
(C) \(3\)
Step-by-step Solution
Detailed explanation
In scientific rotation every number is expressed as a \(\times\) \(10^{\mathrm{b}}\), where \(\mathrm{a}\) is between 1 and \(10, \& \mathrm{~b}\) is any positive or negative exponent. The power of 10 is irrelevant to the determination of significant figures. Thus, in…
