1.it is non-zero OR

2.it is a zero between 2 significant numbers OR

3.it is a number at the end of a number and to the right of a decimal place.

p = m/v,so the problem is 23.523g/17.5L=

1.344p

All the digits are significant.

Hope this is helpful,IM me if you need a more detailed answer.

Anything that’s not a zero is significant.

Zeroes between two non-zeroes are significant.

And all zeroes to the right of the decimal point and last numbers in the decimal place are significant.

23.523 has 5 significant figures.

17.5 has 3 significant figures.

730064 has 6 significant figures

7300 has 2 significant figures

300740 has 5 significant figures

I hope this works for you.

When trying to find how many significant figures a result will have, like in this problem, you can only be as accurate as your LEAST accurate data.

In this case, your least accurate data is 17.5 liters. So your result will only have three significant figures.
