Calculate appropriate v/v dilution using the formula C1V1 = C2V2 where C represents the concentration of the solute, and V represents volume in milliliters or ml. An example would be combining 95 percent ethanol with water to mix 100 ml of 70 percent ethanol. The calculation is 95% X V...
Re: How to find concentration « Reply #3 on: February 09, 2015, 09:39:30 AM » You don't calculate the concentration - you determine it experimentally.Calculation is part of the procedure but without some kind of measurement you can't do anything. Logged ChemBuddy chemical calculat...

Due to the 1:1 ratio between KOH and OH-, the concentration of KOH is 10-7.3M The final concentration of KOH is 10-7.2M Because there’s 1L of solution, there is initially 10-7.3 moles of KOH and at the end, 10-7.2 moles of KOH The amount added would therefore b...
Whether you are exploring organic chemistry, biochemistry, or environmental chemistry, a well-chosen chem topic ensures that your paper will contribute meaningfully to your academic field. When picking a research topic, consider its feasibility and relevance. Ensure the topic is broad enough for ...
The detected intensities from the mass spectrometer were calibrated by linear regression, and then the equation of the calibration curve was used to calculate concentrations of dissolved ions in the electrolyte. The dissolution rate of Al is converted by subtracting the solute contribution from the ...
Different models are available.In this tutorial, we will choose type I environmental assessment for both local scale and regional scale.Usually both local scale and regional scale are chosen to calculate both the regional concentration (PECregional) and the local concentration (PEClocal). In ...
It says to assume 1mL solution = 1g solution Is this referring to the solution or just the water? If it is referring to the solution, would the mass be 75.0g? q(soln)=m(soln)cΔT =75.0 x 4.184 x (27.21-25) =693.5J =0.6935kJ ...
