1 Practical report: Determination of concentration using a standard curve Introduction Spectrophotometer is an instrument that confirms the measurement of specified wavelength of light that passes through medium. The measurement of light absorbance by a solution is also done with spectrophometer. Absorption spectrum Spectrometers are mainly and widely functional in identifying the components of solutions that helps determine the components’ concentrations. Compounds are experimentally identified

Example 1: Does the curve y = 2x3 – 2 crosses the x-axis between x = 0 and x = 2? Solution: Solving for the given values of x‚ at x = 0‚ then y = 2(0)3 – 2 = -2‚ the curve is below the x-axis at x = 2‚ y = 2(2)3 – 2 = 16 – 2 = 14‚ the curve is above the x-axis‚ So the curve crosses the x-axis between x = 0 and x = 2 since y = 2x3 – 2 has a solution found between this interval. Example 2: From the curve y = x5 - 2x3 – 2‚ is there a solution between x = 1 and x = 2? Solution: Using the given

Meanwhile‚ there are only two factors that stimulate the same effect on the LM curve: alterations in money supply and autonomous shifts in money demand (Revier‚ 2000). A rise in money supply creates an excess of money on the initial LM curve‚ thus shifts the LM to the right as observed in Figure 1.3 (Revier‚ 2000). The occurrence of excess demand may be eliminated by rising the interest rate‚ causing the level of money demanded to fall until is meets the quantity of money supplied again (Revier‚
