If HCl acid particle is completely dissociated in aqueous medium into a hydronium ion and chloride ion then what is the molarity of hydronium concentration when 5.00g of the acid gas dissolves into 300 cm^3 of water?. (assuming no change in volume)

or:Molarity means moles per liter. 5.00g/300cm^3 = 5.00g/0.3 = 16.666...g/L so now all you have to is look up the molar mass of HCl. You do have a printed periodic table, right? You can get the information at www.chemicalelements.com/index.html but you really need your own printed copy to carry with you. It will be a primary reference for everything you do. H - 1.00794Cl - 35.4527--------------- ADD...... 36.4606416.66666/36.46064 =0.4571 mole/literGet a ruler in your hands. Measure things until you start to understand how a ruler works. Measure some stuff and figure out where the center is. Say you measure a book and it's 7/8\" thick. You look at your ruler and see that every eighth is divided into two sixteenths, so obviously half of 7/8\" is going to be 7/16\". If you write that out you have 1/2 x 7/8 = 7/16. And you notice that 1/2 is divided into 2/4 and then into 4/8 and so on, so you can convert anything to anything by multiplying all the numbers on top and then all the numbers on bottom.Other rulers are divided into 10 and 100 parts. But an inch is still an inch, so anything on one ruler can be translated to the other ruler. A half inch on one ruler is 5/10 or 50/100 on the other. An eighth inch is just 12.5 marks when you have 100 marks per inch. A metric ruler divides an inch into 25.4 parts, so a half inch would be 12.7 of those parts. Pretty simple, isn't it? Practice this a bit and people will think you went to wizard school.
