I don't see a question.
I’m confused how to do it. Because when I search it up, it’s like they divide the answer by like 100.
I'm somewhat confused by your confusion but on my calculator I get
569 mol * 54.938 g/mol = 3.1259722 g which rounds to 3.12E4.g which is to three(3) significant figures.

And 7.098 * 10^4/ 22 g/cm^3 = I guess you meant
7.098 * 10^4 g/22 g/cm^3 = 3.22636E-1 which rounds to 0.32 which is to two significant figures.

If I have misunderstood, please clue me in.
