Question

Determine the number of significant digits in the measurement.

0.79 cm
a.
3
b.
4
c.
2
d.
1

Answer 1

The answer is 2. Significant figures is the amount of numbers after the decimal that matter. For instance 0.79 has two and 0.790 also has two because the zero on the end does not change the value. However if u put the zero before the 7 (0.079) then u have three significant figures because that does change the value
