Question

Measurements 1. Every experimental measurement is associated with a degree of uncertainty. In the following value, what digit is estimated. 1.568 g

Answer 1

Answer: 6

Explanation:

The value given, 1.568 g, has four digits after the decimal point. In this case, the digit in the thousandths place (the third digit after the decimal point) is estimated.

To determine the estimated digit, we look at the next smallest unit of measurement. In this case, the next smallest unit is the hundredths place (the second digit after the decimal point), which is 6 in the given value.

Since the digit in the thousandths place (the third digit after the decimal point) is 8, which is greater than 5, we round up the digit in the hundredths place. Therefore, the estimated digit in the thousandths place is 6.

In summary, the estimated digit in the value 1.568 g is 6.
