When it is between non-zero digits, e.g.: 504 or 2005When there is one or more zeros after the last non-zero digit AFTER the decimal point, e.g.: 3.40
When there are zeros after the last non-zero digit in a whole number, one or more zeros MAY be significant, e.g.: 500. But if you have to guess, you should consider such zeros to be non-significant.

No, a leading zero is NEVER a significant digit.
When they are between two non-zero digits or if there are after the decimal point. For example, the 0 is not significant in 1340 but it is significant in 1304 or 1340.0
Only one of them is significant. The leading zero (zero to the left) is not significant. The trailing zero (rightmost) is significant. To recap, only the zero following the seven is significant. See the related links for a really good article on significant digits.
I'll assume you're asking about zeros. Zeros appearing anywhere between two non-zero digits are significant. In the other two cases they could be, but are not necessarily significant.
0.7 has one significant figure. Any non-zero digit is significant (165 has three significant figures). Any zero between non-zero digits is significant (304 has three significant figures). Any zero to the right of a non-zero digit in a number which includes a decimal point is significant (10,000 has one significant figure, .0001 has one significant figure, but 100.0 has four significant figures, as does 0.001000). In this case, only the 7 is significant.
0.02 has two significant figures. The leading zero is not significant in this case as it is considered a placeholder.
No, a leading zero is NEVER a significant digit.
All of the digits are significant digits in this case. A zero between other (non-zero) digits is considered significant.
Zero is considered a significant digit when it is to the left or the right of the decimal point. It is also a significant digit when it follows a non-zero digit or when it is between two digits.
235 has 3 significant figures.This is because all three digits are non-zero numbers, and all non-zero numbers are considered significant.
No. 0.0000123 has three significant digits.
The significant figure for 20kg is 2, as the trailing zero(s) after the whole number are not considered significant in this case.
Yes, 370.0 has four significant figures because zeros between non-zero digits are considered significant.
There are two significant figures in 2.0. The zero after the decimal point is considered significant in this case.
The number 051 has two significant figures. The leading zero is not considered significant because it is only serving as a placeholder.
When they are between two non-zero digits or if there are after the decimal point. For example, the 0 is not significant in 1340 but it is significant in 1304 or 1340.0
5 of them. All non-zero digits are considered significant. Zeros appearing anywhere between two non-zero digits are significant. Leading zeros are not significant.
