question 1\nround off 3.72593 ml to three significant figures.
Answer
Explanation:
Step1: Identify significant figures
The number is 3.72593. We want three significant - figures.
Step2: Look at the fourth digit
The fourth digit after the decimal point is 5. According to the rounding - off rule, when the digit to be rounded is 5 and the digits after it are not all zeros, we round up.
Step3: Round the number
The first three significant figures are 3.72. Since the fourth digit is 5, we round up the 2 to 3. So the number rounded to three significant figures is 3.73.
