How many significant figures are there in each of the following values? (c) 75.0

Accepted Answer

Welcome back everybody. We are tasked with finding how many significant figures there are in this number right here. Keep track of them. I'm gonna start a list and I will list any digits that are significant. So let's go through our rules here First. Any non-0 digits are always significant. So let me write this a little bit bigger here. We have that. Both five and four are non zero digits. So those will go in the list. Now we are told that any zeros between two significant digits are significant. We don't have any zeros in between uh these two numbers. So that does not apply. We're told that any final zeroes or trailing zeros in the decimal portion. So looking at this area right here are significant meaning this zero will be significant. Now, what about these Leading zeros? Right here, Leading zeros are not considered significant figures. So in total we have 54 in that last zero has significant figures, meaning we have three significant figures in our number corresponding to our answer choice of B. Thank you all so much for watching. Hope this video helped. We will see you all in the next one
