- 1). Mark the given temperature on the x-axis. If the labels on the x-axis are not precise enough to know exactly where the given temperature lies, estimate it.
- 2). Trace a line straight up from the temperature mark on the x-axis until it intersects with the graph of the solute.
- 3). Trace a straight line horizontally towards the y-axis. The value at which this line intersects the vertical axis is the mass of the solute that will dissolve in 100 g of water.
- 1). Mark the given solubility on the y-axis. If the labels on the y-axis are not precise enough to know exactly where the given mass of solute that will completely dissolve lies, estimate it.
- 2). Trace a line horizontally from the solubility mark on the y-axis until it intersects with the graph of the solute.
- 3). Trace a straight line directly down towards the x-axis. The value at which this line intersects the horizontal axis is the temperature at which the given solute has the specified solubility.
- 1). Mark the given temperature on the x-axis. If the labels on the x-axis are not precise enough to know exactly where the given temperature lies, estimate it.
- 2). Mark the given solubility on the y-axis. If the labels on the y-axis are not precise enough to know exactly where the given mass of solute that will completely dissolve lies, estimate it.
- 3). Trace a line straight up from the temperature mark on the x-axis until it has passed the solubility mark on the y-axis.
- 4). Trace a line horizontally from the solubility mark on the y-axis until it intersects with the graph of the solute. This intersection should be very close to the graph of the solubility of a solute. If not, then you need to repeat these steps on the solubility graph that includes the solute you are searching for.
