The questions given are posted, then the second time, they are given with answers. How does the information in the question lead to these answers?

2. When a protein solution is heated the proteins can denature and precipitate as colloidal particles. The particle size distribution of the particles depends on the conditions of the treatment. A protein solution was treated at 80C for 24h after which the following particle sizes were obtained: a. What is the number weighted (r(1,0)) average radius? b. What is the area weighted (r(3,2)) average radius? c. What is the volume weighted (r(4,3)) average radius? 2.
