A solution has mainly two components a solute and a solvent. The amount of solute measured in moles available in the solution having a volume of 1 liter gives us the definition of molarity.Answer and Explanation: We have The volume of NaOH solution = 25.5 mL = 0.0255 L The ...
We are given the NaOH solution with 3.25 M concentration. The unit of concentration is molar or mol/L.This means that 3.25 moles of NaOH present in 1...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can...
To calculate the number of moles of methanol in 5 liters of a 2 m solution, we can follow these steps:Step 1: Understand the meaning of 2m solution A 2m (2 molal) solution means that there are 2 moles of methanol (CH₃OH) in

(i)Use the formul a below to calculate the thermal energy change q for your thermometri c titration.q= mcAT Assume that the density of the reaction mixture is 1.00 g cm-3 and that its specific heat capacity c is 4.18Jg-1 C-1.q =...J [2](ii) Use your answers to (b)(iii) ...
Calculate the amount of the component in moles using the formula, Amount (in moles) =mass (compound)/molecular mass (compound). In our example, Amount (NaOH)=0.5 g /40 g/mole= 0.0125 moles. Step 3 Convert moles to millimolesusing the following proportion: 1 mole corresponds to 1 milli...
You were told above that in chemical reactions, atoms combine in terms of moles, which you now can get from their masses. For example, in a calcium chloride (CaCl2) solution, the dissociation reaction can be expressed: CaCl2(aq) ⇌ Ca2+(aq) + 2Cl–(aq) ...
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...
Neutralization reactions can be acidic, neutral, or basic in nature, depending on the strengths of the acid and base involved in the reaction. Answer and Explanation: The moles of the acid and base need to be calculated to determine which component has been ...
350 ml of a 0.02 molar solution of NaOH is added to 500 ml of a 0.03 molar solution of HCl. Calculate the pH for the final solution. Step 1:Identify the acid and base in the solution. Acid-HCL, Base-NaOH Step 2:Convert both the acid and base into moles and subtract the...
