One mole of chlorine (Cl) is 35.4530 g/mol. If your solute is table salt (NaCl), it is a compound of sodium and chlorine. To find the molar mass of NaCl, you add the mass of each element. Work out 22.9898 + 35.4530 = 58.4538....
you can find the molar solubility which is the number of moles that can be dissolved per liter solution until the solution becomessaturated. The units are given in moles per L, otherwise known as mol/L or M.
Such solute trapping of Mg in Al oxide has been reported previously40,54. Both Mg and Al have a very high affinity to oxygen, with Mg having an 8% higher one, explaining its preferential oxidation54,55,56,57. During the extended oxidation of binary Al-Mg alloys, it was shown that Mg...
Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. ...
I also struggled to find the moles. What moles do I find? the NaOH or HCl? I wasn't sure, but I just used the HCl. n(HCl)=0.025L x 0.5M =0.0125mol ΔH=-0.6935kJ/0.0125mol =-55.48kJ/mol Could you help me understand how to find the mass and which moles to use? Thank you...
The term "molar solution" refers to the corresponding molarity of a solution. For example, a two molar solution means the molarity of the solution 2 mol/L. Alternatively, it suggests the existence of two moles of solute in one liter of the solution....
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...
Converting from mmol/L to mg/L requires: 1) Converting mmol to mol, so you can find the number of moles in the solution. 2) using the molar mass of the solute to find the mass of the solute in solution. 3) Converting grams to milligrams to find the conce
Find the mass in grams of 0.000305 moles of mercury. How do you do stoichiometry limiting reactant problems? What is the mass of a liquid with a density of 2.12 g/mL and a volume of 53.0 mL (to the nearest gram)? Calculate the number of moles of solute in 8.00 x 102 mL of a ...
