Given a reaction with the following data, calculate the rate constant (k) of the reaction:2 A + 3 B → CAt a particular temperature, the initial concentration of A was 0.2 M and the initial concentration of B was 0.5 M. After 30 minutes, the concentration of A decreased to 0.1 M while the concentration of B decreased to 0.3 M. The reaction is second order with respect to A and first order with respect to B.

A chemistry student is given a sample of a solution containing a known amount of sodium chloride (NaCl) dissolved in water. The student needs to determine the concentration of the NaCl in the solution, using mass balance calculations. The student has access to a balance and other necessary laboratory equipment. What is the concentration of NaCl in the solution given to the student? How much NaCl is present in the solution, and how much water was used to dissolve it?
