The required mass should be in a single text file (output.txt). Only two decimal places should be included in the output.txt. Example: *input.txt* compound,liter,molarity NH4Cl, 0.1, 2.5 NaCl, 0.5, 0.25 Na2CO3, 0.75, 1.25 *output.txt* 13.37  7.31 99.36

Design a modular program in Python to process payroll for all hourly paid employees, save all the data into a text file and make a backup file as well. The program should allow user enter each employee's ID, name, hours worked, and hourly pay rate. And then calculate gross pay with overtime hours(hours beyond 40) paid 50% more. And then the program should display pay statement for each employee and store them into a same text file. The program should display total number of employees, total number of hours worked by all employees, and total gross pay and save them at the end of the same text file as well. The program should contain the following functions: main(), get_employee_info(), calc_gross_pay(hours, rate), display_pay_statement(emp_id, emp_name, hours_horked, hourly_pay_rate, gross_pay), save_pay_statement_to_file(file_object, emp_id, emp_name, hours_worked, hourly_pay_rate, gross_pay), save_summary_to_file(file_object, number_of_employees, total_hours_worked, total_gross_pay).…
