Question

Express the answers to these problems in the correct number of

significant figures.
6. 0.042 m. + 1.33 m =
7. 8.90 g - 4.555 g =
8. 60.0 L/5 L =
9.
7.8 cm x 3.5 cm =
10.
5.63 +4.245 - 8.9 =

Answer 1

I solved the questions then counted how many significant figures in each answer

eg,

0.042m+1.33m =1.372m

1.372 has 4 significant figures

that's how you do others

Step-by-step explanation:

6. 1.372m = 4 significant figures

7. 4.345g = 4 significant figures

8. 12L = 2 significant figures

9. 27.3cm = 3 significant figures

10. 0.975 = 3 significant figures
