Question

5. Density equals mass divided by volume. If a

chemist is calculating the density of a
substance with a known mass of 23.523 g and a
known volume of 17.5 L, how many significant
figures will the result have?

Answer 1

3 significant figures

Step-by-step 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.
