When something burns it usually means something is being damaged or being changed such as colour, smell, or shape.
The simplest way to use the periodic table to identify<span> an </span>element<span> is by looking for the </span>element's<span> name or elemental symbol. The periodic table can be used to </span>identify <span>an </span>element<span> by looking for the </span>element's<span> atomic </span>number<span>. The atomic </span>number of<span> an </span>element<span> is the </span>number of<span> protons found within the atoms of that </span>element<span>.</span>
Given, the density of water is 0.9975 g/ml. Density of water is mass of water per unit volume. Mass of 1 ml of water supposed to be 0.9975 g from density of water. So, mass of 10 ml of water is (0.9975 X 10) g= 9.975 g. From graduated cylinder, mass of 10 ml water is measured to be 9.955 g. So, error for mass of 10 ml water= (9.975-9.955)=0.02 g. Percentage of error for 10 ml water is 
= 0.2. Error in the mass for the 10 ml of water is 0.2 %.
