Question

Please help guide or explain how I would graph this? Thank you so much

IV. Data Table • Fill in the remaining columns on your data table. Calculate the solubility at each temperature by dividing the mass of KNO, used by the volume of solution at that temperature. (Watch sig tig! V. Graphing the data - Temperature (°C) on the x-axis and Solubility (g KNO/mL solution) on the y-axis • Orient graph paper as noted "up" with long dimension on the left. Label the X-axis (bottom) as Temperature. Include units in parentheses. Label the graph lines on the x-axis with appropriate numbers. Your temperature should range from 30 to 90 °C, using the entire axis. Label the y-axis (left) as Solubility. Include units in parentheses. Label the graph lines on the y-axis with appropriate numbers. Your solubility should range from 0.0 to 1.2 g/mL, using the entire axis. Add a title describing the experiment at the top. Plot ALL of the data points. (8 points total). Make sure you are using data from the correct columns. Use a ruler to draw a "line of best fit" - a smooth, solid line that passes through (or comes close to) your plotted data points. Do not try to "connect the dots" - try to sketch the general Shape of your data. Extrapolate (extend) the line of best fit backwards to 30 °C and forwards to 90°C as a dashed line. Estimate the solubility of KNO, at 30°C based on the trend of your line. Estimate the solubility of KNO, at 90 °C based on the trend of your line. VI. Final Observations & Waste Disposal • After your test tubes have cooled for several minutes, make careful observations of the cooled solution and record them on your report sheet. Answer the questions about the types of solutions present at different times and how solubility is affected by temperature. The KNO, solutions may be disposed of by flushing with plenty of water in the sink. Be sure to rinse out your test tubes thoroughly to prevent a salt residue. •

Answer 1

Take temperature on the x axis of the graph( horizontal line) . Take a line on the bottom half of the paper as x axis.

Take solubility on the left side vertical line joining the x axis .

Divide the x axis into 12 parts each of 5°C and divide the y axis into 12.parts each of 0.1 g/ml.

Plot the points according to your table. Join the solubility to each temperature.

Now the points are connected and extended to find the solubility at 30 and 90°C . And the graph will be a straight line.

I am attaching a rough example graph.

Solubility (g/ml) OM 20% 30 35 yo Temporature (°C) → Peach

I hope it helps.
