Add or subtract the following measurement be sure each answer you enter contains the correct number of significant digits
5.70mL-1.5mL=?mL
4.2 mL
To subtract the following measurements and maintain the correct number of significant digits, follow these steps:
Step 1: Align the decimal points of the numbers.
5.70 mL
- 1.5 mL
Step 2: Extend the less precise measurement to have the same number of decimal places as the more precise measurement.
5.70 mL
- 1.50 mL
Step 3: Subtract the numbers as usual.
5.70 mL
- 1.50 mL
----------
4.20 mL
Step 4: Round the result to the least number of decimal places in the given measurements, which is 2 decimal places in this case.
The final answer is 4.20 mL.
