K1.6 PROGRESSIVE MASS-MASS PRACTICE PROBLEMS
The problem that follows is similar to Q1, but slightly less guidance is provided. Solid CuI is precipitated from a mixture of ionic solutions and you are required to find its mass.
Since examination questions and practical situations may or may not provide much assistance with the procedure(s) to adopt, it is important to be able to complete successfully questions like Q3 - Q5 without significant guidance. This is the purpose of the next couple of problems. If you apply the steps considered above, you ought to encounter little difficulty finding correct solutions providing, of course, you are not let down by poor arithmetic.
