A 1 micromolar (µM) solution contains 1 µmol of solute in 1 liter of solution. This is equivalent to 0.000001 (1 x 10^-6) moles per liter. A 1 picomolar (pM) solution contains 1 pmol of solute in 1 liter of solution. This is eq...
Calculate moles of KOH and Mg(NO3)2. From stoichiometry of reaction find moles of reagent in excess and moles of Mg(OH)2 and KNO3. Neglect Mg(OH)2 (precipitate) and finally calculate concentration (volume was changed). Logged AWK
2.600 g100 mL⋅10 mL=0.2600 g2.600 g100 mL⋅10 mL=0.2600 g After that I would calculate the moles of NaOH used 0.1000 mol/L⋅21.60 mL⋅1 L/1000 mL=0.002160 mol0.1000 mol/L⋅21.60 mL⋅1 L/1000 mL=0.002160 mol Then I use this to find the moles of acid present...
Molarity is probably the most commonly used unit of concentration. It is the number of moles of solute per liter of solution (not necessarily the same as the volume of solvent!). Example: What is themolarity of a solutionmade when water is added to 11 g CaCl2to make 100 mL of solution?
A good volume of NaOH to use per titration is 15 mL. From this molarity and volume, the moles of N Explain what is meant by the equivalence point in the titration of HCI solution with NaOH solution. Which of the following titrations wi...

This moles/liter figure is a little cumbersome, so we can convert it to µM units by multiplying the value by 10^6 to get a final concentration. C = 131 µM What if we want to calculate the concentration of oligonucleotide probes with fluorescent dye labels?...
volume = moles / concentration so it should be 1.76 x 10^-3 / 0.02? therefore the theoretical value is 0.0881937116 L x 10^3 should give the answer in mL but I got 88.19mL?! I'm confused on where I went wrong.. Thankyou for your time....
