A student wanted to determine the concentration of NaCl in a sample of water from Mission Bay for use in a Marine Studies project. The data table from her lab notebook is shown below. Use Excel to construct a standard curve, being sure to put concentration of NaCl on the x-axis. Instructions for how to graph with Microsoft Excel are given as pdf and also in lab3. The r-squared value for the equation of the line is: . (Please report answer to 3 places after the decimal.)
