Calculate the of the solution that results from each of the following mixtures: Part A - 55.0 mL of 0.15 M HCHO2 with 70.0 mL of 0.13 M NaCHO2 Part B - 135.0 mL of 0.13 M NH3 with 260.0 mL of 0.13 M NH4Cl
What is the molarity of a sodium chloride solution if 2.45 grams of NaCl is dissolved in 250 mLs of water? C. How many grams of solute are in 1.75 Liters of 0.460 M sodium monohydrogen phosphate? Please explain
To what final concentration of NH3 must a solution be adjusted to to just dissolve .060 mol of NiC2O4 (Ksp: 4x10^-10) in 1L if sikution. Neglect the hydrolsis of C2O4 because the solution will be quite basic.
