How many significant figures are in 7.0?
Answer (3)
There are two significant figures in 7.0 because 7.0 is the greater than 1. If there is a decimal number that is less than 1, all figures are significant except the leading zeros after its decimal point and f or a decimal number that has one or more zeros at the end, the very last zeros count as significant. so, 7.0 is the decimal number, we count both figure 7 and 0 and a significant figures.
Trailing zeros to the right of the decimal ARE significant. So, in 7.0 , there are 2 significant figures.
Another example: There are FOUR significant figures in 92.00
The number 7.0 has two significant figures: '7' is a non-zero digit, and the trailing '0' after the decimal point also counts as significant. Therefore, both contribute to the total count of significant figures in this measurement.
