You have 1.0 mol of HCl and you want to dilute it to 0.1 mol. How many mL out of 50 should it take up? Calculate the molarity of the 37% (v/v) of HCl. Calculate how many ml of 37% HCl is needed to make 1 L of 0.1 M HCl. What is the molarity of 26.7 moles of HCl i...
A solution of aqueous substance (molar mass 90.8g/mol) has a molarity of 1.3M and density 1.08g/mL. What is its molality? Fill in the blanks, dealing with concentrations of solutions. Solute: NH3, Grams solute: 30 g, ...
To solve the problem step by step, we will calculate the molarity and mole fraction of ethanol after diluting it with water.Step 1: Calculate the mass of ethanol Given: - Volume of ethanol = 100 mL - Density of ethanol = 0.8 g/
To solve the problem step by step, we will calculate the pH of the resulting solution after mixing two solutions of sulfuric acid (H₂SO₄).Step 1: Determine the molarity of H₂SO₄ in each solution We have two solution
(Edit: Ok time to put up working:) Millimoles/L of Cl ions Find moles of NaCl and KCl as these have the Cl ions. 5.84/58.4 = 0.1 moles 2.98/74.6=0.03994 moles therefore there are: 0.13994moles of Cl in solution Molarity = 0.13994/4 = 0.034985M ...
The term "molar solution" refers to the corresponding molarity of a solution. For example, a two molar solution means the molarity of the solution 2 mol/L. Alternatively, it suggests the existence of two moles of solute in one liter of the solution....
There are 3 steps to solve this one. Solution Share Step 1 Number of moles (in terms of molarity)=molarity× volume (in Liters) Explanation: Mass= number of moles× molar mass Part 1) molarity=0.152MVolume =423.8mL×1L103mL=0.4238LSubstituti...
Answer and Explanation:1 We were given the following: 274 mL of a 0.680 M NaCl solution 72 mL of a 0.220 M NaCl solution 1. First, we have to calculate the number of moles...
5. Now measure the volume at the level of the AgNO3 precisely, and record it as the “Initial Burette Reading on your report. Also record the exact molarity of the AgNO3 (ag), which is labeled on the stock bottle. 6. The volumetric pipette us...
