Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Hi :) It's a significant figures question - I was wondering if you count 12.4kg as 3 significant figures or not. The key answers (written in the photo) for the question didn't seem like they counted 12.4kg as sig figs... or (1) did and (2) didn't, in order to match the sig fig for the money value of $1255 (4 significant figures...)...?
A density bottle test on a sample of dry soil gave the following results:Mass of 50ml density bottle empty (g) = 25.07Mass of 50ml density bottle+20g of dry soil particles (g) = 45.07Mass of 50ml density bottle+20g of dry soil particles, with remainder of space in bottle filled with water (g) = 87.55Mass of 50ml density bottle filled with water only (g) = 75.10Calculate the relative density (specific gravity) of the soil particles. Round your answer to 2 decimal places.
