Question

Disregard the _________ to ________ numbers written as __________ (1st, 2nd) and ________ only the __________in ___________ _________ (1, 2).

Answer 1

The question is about significant figures in Chemistry, which are digits that contribute to the precision of a scientific measurement. The rules provided help determine which digits are significant, considering the presence of leading, trailing, and middle zeros, and the overall number structure.

Step-by-step explanation:

The question is related to the concept of significant figures in Chemistry, particularly when dealing with the representation of numbers and determining which digits in a number are significant. Significant figures are important in scientific measurements because they convey the precision of the measurement.

According to the rules provided:

• All three numbers are significant (rule 1).
• The leading zeros are not significant (rule 3).
• The trailing zero is significant if a decimal point is present (rule 5).
• The middle zeros are significant if they are between non-zero digits (rule 2).

These rules help us identify the important digits, also known as significant figures, in any given number that is reported in a scientific context.
