Answer:
3 significant figures
Explanation:
23.523 has 5 significant figures that is the figures 2,3,5,2,3
17.5 has 3 significant figures that is the figures 1,7,5
Density is mass/volume (given in question)
Density is 23.523g/17.5L= 1.34417142857143 g/L (Without rounding off the answer)
This has 15 significant figures
However, for precision, the result is 1.34 g/L which has 3 significant figures.
