How many grams of hydrochloric acid are needed to make a solution of 2 molar?
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
10 grams per liter HCl solution preparation?
try adding ten grams to every liter
What is the pH of a solution with 1 mole of hydronium ions per liter?
It has a pH of 0.
What is the difference between 0.5 mole HCL and 0.50M HCL?
Basically it is the difference between a quantity and a concentration. 0.5 mole HCl means approximately 17.73 gram of HCl. 0.50M HCl means that quantity of HCl per litre of solution. So if you had two litre of 0.50M HCl solution, you would have 35.46 gram of HCl, but 0.5 mole HCl always means just 17.73 gram. There are two other issues -- the first is an issue of precision. 0.5 mole in scientific practice means anything between 0.45 and 0.55 mole, that is (in this case) a ±10% margin of error. So 0.5 mole HCl might be anywhere between 16.0 and 19.5 gram. But 0.50M HCl is much more tightly constrained -- between 0.495 and 0.505 mole per litre, meaning between 17.55 and 17.91 gram per litre. The second is, of course, that with any chemical element whose symbol is 2 letters, like Cl, the second letter must be lower case -- Cl, not CL.
A solution of sodium carbonate Na2CO3 that has a molarity of 0.0100 M contains equivalents of sodium ions per liter of the solution?
0.01 mole
What has the pH of 1?
pH=1 means the solution contains 0.1 mole per liter H+ ions. Strong acids like hydrochloric acid (HCl) or sulfuric acid (H2SO4) dissociate completely in water so 0.1 mole of HCl (= 3,65 g per liter) has a pH=1. For sulfuric acid 0.1 mole = 9.8 g per liter give pH =1

what is molarity?
In chemistry (as opposed to dentistry!), molar is a unit of concentration. Molarity is defined as the number of moles of solute per liter of solution. It is often abbreviated M.If you have a 1.0 M solution of HCl, there is 1 mole of HCl per liter of the solution.See the Related Questions for more about solutions and concentrations.

What does 1 m?
M or Molarity is what is used to describe the concentration af acids. 1 M means that there is one mole of substance per every liter of sulution so if the molarity of HCl (hydrochloric acid) is 1 then there is 1 mole of HCl per every liter of the hydrochloric acid.
What is the pH of a solution with 1 mole of hydronium ions per liter?
It has a pH of 0.
What formula do you use to find a solution stregth?
Your question doesn't have a single answer. In Chemistry solution strength is usually calculated in moles pe liter of mole per kilogram or as a mole fraction ( moles per mole) but can also be mass per liter, mass per mass, volume per volume, percent by mass, or percent by volume.

0.01 mole
How to make a standard solution?
A known quantity of a substance is dissolved in solution for a standard solution. This is expressed as units of mole per liter, moles per cubic centimeter, or in terms of that particular titration.
What is an explaination of 0.01 M hydrochloric acid?
1M Hcl contains 36.5 g of HCl per liter of water. 0.01M HCl thus contains 0.365 g of HCl per liter.
If 1.25 grams of pure CaCO3 required 25.5 mL of a HCl solution for complete reation what is the molarity for the HCl solution?
When calcium carbonate (CaCO3) reacts with hydrochloric acid (HCl) the reaction is:- CaCO3 + 2 HCl -> CaCl2 + H2O + CO2 The weight for 1 mole of calcium carbonate is the atomic weight in grams or 40.8 + 12.011 + 3 x 15.9994 = 100.8092 grams 1.25 grams of CaCO3 is therefore 1.25/100.8092 or .0124 mole There must have been twice this many moles of HCl in the solution or 0.0248 mole. The molarity of the solution is the number of moles per litre so with 0.0248 in 25.5 ml there must be .97 mole in 1 litre. The HCl solution must therefore be .97 molar
