JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
Which of the following have same number of significant figures? (A) \(0.00253\) (B) \(1.0003\) (C) \(15.0\) (D) \(163\) Choose the correct answer from the options given below
- A \(A, B\) and \(C\) only
- B \(C\) and \(D\) only
- C \(A, C\) and \(D\) only
- D \(B\) and \(C\) only
Answer & Solution
Correct Answer
(C) \(A, C\) and \(D\) only
Step-by-step Solution
Detailed explanation
All non zero digits are significant. \(0.00253\) \(\text { Significant figures }=3(2,5,3)\) \(1.0003\) Zeros between non-zero digit are significant. Thus,\(1.0003\) has \(5\) significant figures. \(15.0\) Significant number \(=3\) \(163\) Significant number \(=3\) Options (3) -…
