Calculate the van't Hoff factor (i) for CuCl_2, which is the number of particles the solute dissociates into in solution. Use the freezing point depression formula:ΔTf=i⋅Kf⋅mto find the change in freezing point, whe...
Example: What is the molality of a solution of 3 grams of KCl (potassium chloride) in 250 ml of water? First, determine how many moles are present in 3 grams of KCl. Start by looking up the number of grams per mole of potassium and chlorine on aperiodic table. Then add them together...

Calculate the volume of 5 M stock solution required to prepare 200 mL of a 0.25 M solution. Determine the volume (mL) required to prepare 3.0250 L of a 0.190 M KCl solution using an 8.65 M KCl solution. Calculate the volume of a 20.0 ug/m...
Calculate the solute's formula mass by multiplying each of its elements' atomic weights by the number of that element's atoms in the solute. A mole of potassium chloride (KCl), for instance, has 1 mole of potassium, which has an atomic weight of 39.10, and 1 mole of chlorine, which ...
By assuming Onsager's relation to be valid, ten sets of velocity correlation coefficients were calculated for a ternary system and were used to calculate the VCCs for 134Cs+ ion (present in trace amount) transport in aqueous solutions of CsCl and KCl at 25鈼婥....
It means that for every 100 mL of solution you have 5 grams of KCl. Here is the equation to use when calculating w/v percent for a solution: \(\mathrm{w/v \% = \dfrac{mass\enspace in\enspace g\enspace of\enspace solute}{volume\enspace in\enspace mL\enspace of\enspace total...
For example, a NaCl solution and KCl solution with a conductivity of 10000 umhos/cm will not have the same concentration of NaCl or KCl and they will have a different total dissolved solids concentration. Conductivity is measured through the use of a meter and is usually about 100 times the...
