Question

Determine the number of significant digits in the measurement.. . 80.00 kg

Answer 1

4 significant digits.

Explanation:

We are asked to find the number of significant digits in the given measurement: 80.00 kg.

Let us recall significant digit rules.

• Any non-zero digits are significant. The zeros between two digits are always significant.
• Leading zeros (zeros before non-zero numbers) are not significant.
• Trailing zeros (zeros after non-zero numbers) are significant, if they are after decimal. If trialing zeros without decimal are not significant.

Upon looking at our given measurement, we can see that we have two digits before decimal and two trailing zeros after decimal.

Since trailing zeros are significant, therefore, our measurement has 4 significant digits.

Answer 2

The number of significant digits in the mass measurement of 80.00 kg is 4. This is based on the rules of significant figures. 8 as a non-zero digit is apparentyl significant. Trailing zeros on the right of the decimal are significant numbers. And the zero in between is also significant.
