when an ionic or covalent compound is dissolved in water they break apart into ions through process called dissociation ..the ions get attracted by the water molecules and hence they carry polar charges ..and if there is a conduction of electricity. .then we get to know that a compound is dissociated ..

Hello!
The genetic material of all organisms which is made up of two twisted strands in a double helix is called DNA (DeoxyriboNucleic Acid)
DNA is the basis of all genetic information. It contains all instructions for the development and functioning of all living organisms and some viruses. The main function of DNA is the long-term storage of information to build other cell components like Proteins and RNA. It is composed of two strands with 4 possible bases which are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
Have a nice day!
The significant figures will be 1.
As, weight of acetylsalicylic acid = 0. 4 g
We obtain 400 mg when we convert 0.4g of acetylsalicylic acid to mg.
So, 400 milligrams are worth 0.4 grams when converted to grams.
There is just one significant figure because 0 before a decimal is not significant i.e. 4.
<h3><u>What are significant figures?</u></h3>
The digits of a number that have relevance in relation to the measurement's resolution are known as significant figures. Additionally known as significant figures in chemistry. All experimental measurements are subject to some degree of uncertainity.
