Describe how you would weigh your KHP samples, if you didn’t know about weighing by differences. Mentioning any differences between your method and the method we made you use, explain why we use the technique of weighing by difference.
We shall be happy to look at what you provide us with; i.e., you write it and we'll look at it. Why do you weigh by difference? That minimizes most problems that might arise because of miscalibrated weights.
