What is the molarity of a 98\% H2SO4 by mass solution the density of the solution is 1.83 g mL?
The concentrated sulfuric acid we use in the laboratory is 98\% H_2SO_4 by mass. Calculate the molality and molarity of the acid solution. The density of the solution is 1.83 \frac{g}{mL} answers are 5\times10^{-2} m, 18.3M.
What is the volume of 98 H2SO4?
100 The weight of sulfuric acid = 28.8 x 98 x 98 = 2880 Density – Mass Volume = 1.8 g/ml. Mass Hence, volume of the sulfuric acid solution is a density 2880 g ; = 1600 ml = 1.6 L 1.8 g/ml 206 EAST.
What volume is 98 ww2 H2SO4?
Now, we can calculate the volume of solution. Hence, the volume of acid required is 5.5mL.
What is molarity of 90 H2SO4 solution?
1.8 gm/ml
The molality of 90 \% H2SO4 solution is [density = 1.8 gm/ml ]
What is the atomic mass of H2SO4?
The weight of 2 H atoms is 2 grams (1 gram weight of each), weight of Sulphur atom is 32 grams and weight of 4 O atoms is 64 grams (16×4). Now add up all of them that is 98 grams which is the molar mass of H2SO4. Thus, molar mass of H2SO4 is 98 grams.
How do you calculate molarity?
Calculating Molarity. For that, you need to determine the molecular weight of the solute. Then divide the number of moles by the volume of solvent in liters. The result will be the molarity of the solution. Calculating molarity of a solution is possible if you know its density and molecular weight of the solute.
What is the reaction of H2SO4?
The products of the reaction between barium chloride (BaCl2) and sulphuric acid (H2SO4) are barium sulphate (BaSO4) and hydrochloric acid (HCl). This is known as a precipitation reaction, because barium sulphate is a compound that is insoluble in water.
What normality is concentrated HCl?
Normality Example #2. 36.5 grams of hydrochloric acid (HCl) is a 1 N (one normal) solution of HCl. A normal is one gram equivalent of a solute per liter of solution. Since hydrochloric acid is a strong acid that dissociates completely in water, a 1 N solution of HCl would also be 1 N for H+ or Cl- ions for acid-base reactions.
