1. To calculate integral the f(x) function given as a table the following command should be used: (a) quad; (b) quadl; (c) trapz; (d) integral. Choose all the correct answers. 2. Concentrations of the substances in solutions (mostly in water) are measured in various units, such as ? in mg/m 3 and M in ppm (parts per million). The following expressions convert ? to M (based on 1atm and 25C): where M 1 is the molecular weight of the substance, g/mol. Write and save a script file that calculates and displays the concentration in ppm by the requested (with the input command) values of ? and
