Any zero in a measurement is always significant True Or False

Chemistry
1 answer:
weqwewe [10]2 years ago
3 0

Answer:

False

Explanation:

A significant number is a number that is used to express the accuracy in a measurement. There are some rules that binds the identification of significant figures when reporting a scientific measurement.

  • All non-zero numbers are significant
  • Zeros in between two digits are significant.
  • Zeros to the right of the decimal are significant.
  • Leading zeros are just place holders and are not significant.
  • Trailing zero in a whole number with decimal is significant
  • Trailing zero without a decimal is not significant.

We can see that not all zeros in a measurement is significant. For example, 540 has 2 significant numbers because the zero is not significant but 540.2 has 4 significant numbers.
