The following question is about signifiant figures. So I have 17.82 mL of carbon tetrachloride with a density of 1.60 g/mL and want to calculate the mass. How many signifiant figures should be in my answer? The density of CCl4 was looked up in the literature and found to be 1.60 g/mL I thought the answer should be to three signifiant figures (28.5 g) because both numbers going into the calculation were measured numbers. But I was also told it was 4 (28.51 g) because the 1.60 is the true value of CCl4. Thank you.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
