What is the significant figures for 0.045325​

Answer 1

Answer:

There are 5 significant digits in 0.045325 and they are 4, 5, 3, 2, and 5.

Step-by-step explanation:

Significant digits rules:

• All non-zero numbers count as significant digits

• Leading zeroes (zeroes in front of any non-zero numbers) are never significant digits
• Zeroes in-between non-zero numbers count as a significant digits
• Trailing zeroes (zeroes after all non-zero numbers) count only if there is a decimal

In 0.045325, the two zeroes are leading zeroes and therefore do not count. The rest of the digits, (4, 5, 3, 2, and 5) are all non-zero and therefore count. Thus, there are 5 significant digits in 0.045325.
