1.) [ 6 Points: 2 Point Each]. Solve for x. Give your answer in 3 significant figures. a) 173=4x b) 10.50=1.50logx2 c) 63=ln4x 2. Calcium (Ca) in cow's milk was analyzed using a best-fit graph. Using absorbance of known Ca solutions, the graph of absorbance versus Ca concentration was obtained. Answer the questions that follow. a) [2 Points: 1 Point Each]. What are the: i) slope (m) ? ii) intercept (b) ? b) [5 Points]. A 1\% cow milk sample was analyzed, and its absorbance was found to be 0.254. Use the equation of the line to determine the concentration of Ca in the 1% milk? Include units in your calculations and
