To calculate the normality of NaOH when 2 g is present in 800 mL of solution, we will follow these steps:Step 1: Determine the molar mass of NaOH The molar mass of NaOH can be calculated as follows: - Sodium (Na) = 23 g/mol - O
To calculate the pH of a solution containing 100 mL of 0.1 M HCl and 9.9 mL of 1.0 M NaOH, we can follow these steps: Step 1: Calculate the moles of HCl and NaOH- Moles of HCl: Moles of HCl=Concentration×Volume=0.1M×0.1L=0.01mol ...
Calculate the molar concentration of {eq}I^- {/eq} in a saturated solution of {eq}PbI_2 {/eq} containing {eq}\left [ Pb^{2+} \right ] = 3.75 \times 10^{-4} {/eq} M. (The {eq}K_{sp} {/eq} for {eq}Pb...
0.200 moles of H 2 S 6.82 g 2) 0.100 moles of KI 16.6 g 3) 1.500 moles of KClO 135.8 g 4) 0.750 moles of NaOH 30.0 g 5) 3.40 x 10¯ 5 moles of Na 2 CO 3 3.6 x 10 -3 g Calculate the moles present in: 1) 2.00 grams of H 2 O .111 mol 2) 75.57 grams of KBr ....
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) ...
Then titrated against a 0.05M NaOH solution. For example, if it took 35ml to hit end point. How would I calculate the actual mass of KHP in the initial impure KHP solution. I'm struggling to figure out the moles of KHP in the impure solution. Can you please outline the whole ...
Calculate the new pH of the solution if 0.050 moles of KOH are added to 0.750 L of the solution. Calculate the pH of a 0.79 M methylamine solution. pH = Calculate the pH of a 0.29 M methylamine solution. pH = What is the pH of a 0.17 M solution of methylamine, CH3...
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...
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 compound. The molar mass of elements tells you the molar mass of a compound, so ...
Step 3.Divide the moles of solute found in Step 1 by the liters of solvent found in Step 2 to find the initial concentration of a solution. The equation looks like this: M = 0.50 mol NaOH/0.500 L solvent = 1 M NaOH. In this example, the molarity (M) of the NaOH in the solvent...
