1. Molarity (M): moles of solute/liters of solution or moles/L (mol/L) 2. w/v (g/mL): weight in grams of solute/milliliters of solute 3. w/w: weight in grams of solute/weight in grams of solution (g/g) 4. v/v: volume of solute/volume of solution (L/L) Molar Mass ...
Given: Volume KMnO_4 is 21.45 Volume Fe^{2+} is 25 mL What are the moles of KMnO_4 and the moles of Fe^{2+}? Calculate the molarity of a solution that contains 0.925 moles of KCl in 600 mL of solution. Calculate the molarity of a solution that contains 0.98...
Say you need to make a solution of 1M NaCl for a reaction you are running. How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that comp...
Calculate the molarity of {eq}HCl {/eq} solution from a titration when volume of {eq}HCl \ 25.00 \ mL {/eq} and volume of {eq}NaOH \ 23.00 \ mL {/eq}. Reaction Between Acid and Base: A reaction between an acid solution ans a base solution ...
convert the given concentrations into molarity. here the amount of pcl 5 before the reaction is 6 moles and the volume of the reaction vessel is 1 l. therefore, the concentration of pcl 5 is 6/1 moles/litre = 6 m. step 3 : make a note of the initial concentration and the change ...
Calculate the volume and mass required to make {eq}0.1 M{/eq} solutions of Ammonium Chloride ({eq}53.49 \frac{g}{mol}{/eq}) and Ammonia ({eq}1.0 M{/eq}) Molarity: The molarity is always defined as the number of moles of solute that are d...
Molarity is the ratio of the amount of solute ( in moles) present in one liter of a solution.Answer and Explanation: Given: Mass of {eq}Mg S {/eq}, {eq}m = 20.7 \ \rm g {/eq} Volume of the solution, {eq}V = 899 \ \rm mL = 899 \ \rm mL \times \left( \df...
Calculate the number of moles of sulfuric acid in the total volume you used in the lab(i.e.,8.00mL); Density of sulfuric acid is1.84gmL,and concentration of sulfuric acid is98.0%(ww). Hint: Use the methodology of Question(4)ab...
To solve the problem of calculating the volume of 80% H₂SO₄ by weight required to prepare 1 L of 0.2 M H₂SO₄, we can follow these steps:Step 1: Calculate the number of moles of H₂SO₄ required To prepare 1 L of
