Enter either the number of moles or weight for one of the compounds to compute the rest.1. The central processing unit (CPU) or central processor is the nerve centre of any digital computer system, since it coordinates and controls the activities of all the other units and performs all the arithmetic Answer the following questions: 1. What is the general purpose and function of the CPU?We will now introduce a final method for solving systems of equations that uses determinants. Cramer's Rule will give us the unique solution to a system of equations, if it exists. However, if the system has no solution or an infinite number of solutions, this will be indicated by a determinant of zero.
