6)The equation for molarity states that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. In the first equation, the molarity will clearly be equal to 1.0 M, because there are 1.0 moles of NaCl and a solution volume of 1.0 L.

Use the equation: MconcnVconcn = MdiluteVdilute. Plot the absorbance vs. molar concentration of FeSCN2+. Fit a best straight line to the data, displaying the equation of the line (you can use this equation to extrapolate information later in the lab). Make sure you include a point of zero absorbance for zero concentration in the data. b.

The concentration of charge contributed to a solution by an ion is equal to the molar concentration of that ion multiplied by its charge. For Na+. mol positive charge/L = (1 mol positive charge/mol Na+) X (mol Na+/L) ... Not that this equation is identical to the mass-balance equation. Often a mass-balance equation and a charge-balance equation ...

When you are calculating the concentration of a solution, you must do so by calculating the number of moles of solute dissolved into the total volume of solution. Example 1: Molar mass of salt (NaCl) is 58.5 g/mol, so if you dissolve 58.5g of salt in enough water to make 1.00 liter of solution, you have one mole of solute dissolved per liter of ...
