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 ...
21 (a) A student dissolves 0.6 g of zinc sulfate in 250 cm3 of water.(i) Calculate the volume of the water in dm3.Answer=...dm3 [1](ii) Use your answer to part (a)(i) to help you calculate the concentration of the zinc sulfate in g/dm3.Answer=...g/dm3 [1](b)Zinc...
To solve the problem of calculating the volume occupied by 2.0 moles of nitrogen gas (N₂) at a temperature of 200 K and a pressure of 8.21 atm, we can follow these steps:Step 1: Understand the Given Information We have: - Nu
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...
You can easily measure the packing, or bulk, volume of a given amount of a powder mixture by placing it in a graduated cylinder. But any powder mixture will contain some air, and the packing volume, no matter how tightly pressed in the graduated cylinder
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 ...
moles of KMnO4= 0.15 moles KMnO4 Now the liters of solution is needed. Keep in mind, this is the total volume of the solution, not the volume of solvent used to dissolve the solute. This example is prepared with "enough water" to make 750 mL of solution. ...
Calculate Molarity: moles solute per liter of solution (notvolume of solvent added since the solute takes up some space) symbol: M M = moles / liter Example: What is the molarity of a solution of 6 grams of NaCl (~1 teaspoon of table salt) dissolved in 500 milliliters of water?
Quote from: NewtoAtoms on February 27, 2009, 06:47:16 PM salt = 5.00 x 10-3=7.14 x 10-2M --- 0.070 L (total volume) It is still wrong. Please check what was number of moles of nicotine (your original post contains the correct number) and what was the final volume. Neither 5.0...
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...
