Question

How many significant digits are in the volume measurement 4010,0 mL? A) 2 B) 3 C) 4 D) 5 E) none of the above

Answer 1

Answer: Option (D) is the correct answer.

Step-by-step explanation:

Significant digits are defined as the digits which contribute meaning to the resolution of a number.

For example, if a digit is 40.0 ml then zero placed after the decimal point is not considered a significant because it doesn't contribute any value to the total quantity or number.

But zero placed in 40 will be considered significant because it tells us the number is forty. Hence, in 40.0 there are only 2 significant digits.

Similarly, in 4010,0 mL there are in total 5 significant digits.

Thus, we can conclude that there are 5 significant digits in the volume measurement 4010,0 mL.
