two
By convention, it is assumed that trailing zeros without a decimal point are not significant. For example, 250.0 has four significant figures, but 2500 only has two definitive significant figures.

How many significant digits are in the measurement 2500 liters?

Trailing zeroes are significant digits only if the numerical values have decimal points, otherwise they are NOT significant figures. Examples: 25.00 has 4 significant figures, but 2,500 has 2 significant figures.

What are the 5 Rules of significant figures?

Significant Figures

  • All non-zero numbers ARE significant.
  • Zeros between two non-zero digits ARE significant.
  • Leading zeros are NOT significant.
  • Trailing zeros to the right of the decimal ARE significant.

Why are significant figures important when taking data in the laboratory?

11) Why are significant figures important when taking data in the laboratory? Significant figures indicate the precision of the measured value to anybody who looks at the data. If a weight is measured as being “1100.0 grams”, this means that the mass has been rounded to the nearest tenth of a gram.

How many significant figures does 2300 have?

For example, 2300 looks like it has only two significant figures, but you know (from the problem) it really has three. How do you show this. One way is to use scientific notation like this: 2.30 x 103.
