Calculations for titration.

given 0.2038 gram sample of Ni(NH3)5CL2 dissolved in 0.050L of 0.1503M HCL. Calculate how much 0.09901M NaOH would be required to titrate this sample to a endpoint ? so i know that the HCL in excess converts all the Nh3 in the sample into NH4. so i think...

I have to calculate: 1. moles of NaOH 2. Concentration of NaOH Only problem is, the only data I have is (volume NaOH =27.9 mL). How do I calculate the number or moles if I only have the volume?

I have several more problems to do like this, but if someone could please walk me through this step by step? It is a little pressing, as I need it by tomorrow morning, but please do what you can! Thank you. ------------- Potassium dichromate reacts with...

Heres what we did: Provided with a standard 0.01M solution of sodium carbonate Exactly 25.0cm3 of the approximate 2M hydrochloric acid was very carefully diluted using a bulb pipette. The meniscus was exactly on the line of 25.0cm3 on the pipette. The...

scenario: - 50mL vinegar is diluted to 500mL - 25mL of this diluted vinegar is titrated with 0.1M 26.167mL NaOH solution What is the concentration of acetic acid in this vinegar? ---- I know that no. of NaOH moles = 2.6167x10^-3 moles = no. of moles...

I have done a Mohr titration in 2nd year chem and struggling with the calculations, can someone help please. Have asked my lecturer but been led astray!! Here are the details: Started with an unknown sample (containing .22-.44g of KCl and .50-1.00g KI...

Please help on my titration lab, I've worked on it for a while and it's due later today!! The following list is what I have to do: Moles of NaOH which reacted: Moles of tartaric acid which reacted with OH^-(mol) Mass of tartaric acid present in weighed...
