Best ResponseYou've already chosen the best response.3Nope. 107.94 = 5 sig figs. All the numbers count, even the 0 in the middle of the 1 and 7.

Best ResponseYou've already chosen the best response.3110 = 3 sig figs which is incorrect.

Best ResponseYou've already chosen the best response.1no its two because the last zero doesn't count

Best ResponseYou've already chosen the best response.3Oh my bad. Yes, you are right, 110 has 2 sig figs, but 110. has 3

Best ResponseYou've already chosen the best response.1wait but how he get 110

Best ResponseYou've already chosen the best response.3I `think` he got 110 by rounding 107.94 to 2 decimal places... so rounding 0 to 1 without touching the decimal. Therefore it would become 110. I believe it is wrong because that is excluding all the other numbers as part of the answer, whereas \(\sf 1.1 ~\times~ 10^2\) does not disregard the other numbers, it just states that \(\sf 1.1~\times~10^2\)is a more accurate representation of the answer to 2 significant figures.

Best ResponseYou've already chosen the best response.3\[\sf 1.82~ \frac{g}{mL} ~\times ~ 0.613~cm = 1.11566 ~\frac{g}{mL}\cdot cm = 1.12~\frac{g}{mL} \cdot cm\]

Best ResponseYou've already chosen the best response.3\(\color{#0cbb34}{\text{Originally Posted by}}\) @MTALHAHASSAN2 1.82 g/mL X 0.613 cm = 1.6X10^1 \(\color{#0cbb34}{\text{End of Quote}}\) I was basing it off what you wrote

Best ResponseYou've already chosen the best response.1oh ok the question was thou 1.82 g/mL X 8.6 mL = 1.6 X 10 ^1
