When The total number of grams of KCl (formula mass = 74.6) in 1.00 liter of 0.200 molar solution is = 14.9 g
Calculate of Mass of KCl
The Formula Mass of KCl is = 74.6g/mol
Then, The Molarity is = 0.2M
Now, The Mass conc. is = Molarity x formula mass
After that, Mass conc. = 0.2 x 74.6 = 14.9g
Therefore, The Correct Option is 'B' 14.9 g
When the KCl molecular weight Molar mass of KCl = 74.5513 g/mol This compound is also understood as Potassium Chloride.
