You are given a rock that has perfect cylindrical shape with diameter of 2 cm and length of 5 cm. You measured its porosity and found it to be 26%. You saturated the rock with brine (density of 1.1 g/cc). If the rock is fully saturated and the mass of the saturated rock is 35.91 g. The question is to estimate the grain (matrix) density [16 points] a. Problem Identification: Identify and list all unknown quantities that are needed to be able to calculate the grain density [4 points] b. Solution Formulation: Explain what approach you need to follow to solve the problem. Make sure to include any equations needed [4 points] c. Problem solving: Apply the approach you explained above to find the grain density. Make sure to show your work and include units [4 points] d. Drawing conclusions and physical meaning of the results: I. Based on the results you obtained from the previous steps, what is the mineralogy of the sample (dominant mineral presence) [2 points]
