Answer 18

wait but how he get 110

Answer 19

@Shalante

Answer 20

I `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.

Answer 21

1.82 g/mL X 0.613 cm = 1.6X10^1

Answer 22

Is it right??

Answer 23

No. this is 3 s.f. x 3 s.f = 3 s.f

Answer 24

\[\sf 1.82~ \frac{g}{mL} ~\times ~ 0.613~cm = 1.11566 ~\frac{g}{mL}\cdot cm = 1.12~\frac{g}{mL} \cdot cm\]

Answer 25

Answer 28

Answer 29

okay, then your answer would be 2 s.f

Answer 30

\[\sf 1.82~\frac{g}{mL}~\times~8.6~mL~ =~ 15.652~g~ = ~16.~g\]
