Question

1. which of the following quantities has the greatest number of significant figures: 0.753 20 g, 5.59 g, or 29 000 tons? 5.59 g 29 000 tons 0.753 20 g

Explanation:

Step1: Determine sig - figs for 0.75320 g

Non - zero digits and trailing zeros after a decimal are significant. So, 0.75320 has 5 significant figures.

Step2: Determine sig - figs for 5.59 g

Non - zero digits are significant. So, 5.59 has 3 significant figures.

Step3: Determine sig - figs for 29000 tons

Trailing zeros without a decimal point may or may not be significant. Assuming no additional information, 29000 has 2 significant figures (the 2 and the 9).

Answer:

0.75320 g
