Q7. A solution contains 92.1 g of glycerin, C3H5(OH), and 184.4 g of ethanol, C,H-OH. If the vapor pressure of pure ethanol at 40 C is 0.178 atm, what is the vapor pressure of the solution? (Molar mass of glycerin is 92.1 g/mol and molar mass of ethanol is 46.1 g/mol). Write a C++ program that uses nested for-loops to display a sequence of numbers. The program should ask the user to enter an integer n. The number n should be between 3 and 1000. If the number is not in the range, then display an appropriate message and exit the program. On the first line, the program should display the number n repeated n times. Then on the next line it should display the number n-1 repeated n-1 times, and on the next line it should display the number n-2 repeated n-2 times, and so on for the next lines and only stop when the number reaches zero. Display a star (*) before each line and display a hash (#) at the end of each line. See examples below: 1
