Answer:
53.3
Step-by-step explanation:
The product will be calculated as:
392 × 0.13592 = 53.28064
The correct number of significant figures corresponds to the least number of significant figures in the initial values.
- 392 has 3 significant figures
- 0.13592 has 5 significant figures
The least number is 3 significant figures, hence the result should also have 3 significant figures.
53.28064 should then be rounded to 53.3
This number could also be written as 5.33x10
