6.02 x 1023
Significant figures

It depends on the number of significant figures you are changing to

Explanation:

6.02×1023=6158.46

1 sig fig = 6000

2 sig fig = 6200

3 sig fig = 6160

4 sig fig = 6158

5 sig fig = 6158.5

6 sig fig = 6158.46

When solving significant figures you have to consider the number after each number like in the case of changing to two sig fig the number following one is five and when the number is up to or greater than five you add a value of one to the number before it. But in a case where the number is less than five you just leave it like that like in the case of changing to one sig fig
