Cut 6 equal volumes of plant tissue (potato).#: 2. Dry the plant tissue with paper towel and [[measure ]] the [[mass ]] of each pieceusing an [[Electronic Balance|electronic balance]] or find their [[Volume (Space)|volume]] by [[measuring]] length, noting it downwidth and height with [[ruler]] and multiplying them together.#| style="height:20px; width:200px; text-align:center;" |:3. Use a [[Measuring Cylinder]] to measure 10cm<sup>3</sup> of 1.0M [[sugar]] [[solution]] and pour it into a [[Boiling Tube]].#:4. Repeat step 3 with 8cm<sup>3</sup> of [[sugar]] [[solution]] and 2cm<sup>3</sup> of distilled water to give 0.8M [[sugar]] [[solution]], then 6cm<sup>3</sup> and 4cm<sup>3</sup> of distilled water to give 0.6M [[sugar]] [[solution]], repeating this pattern until there is 10cm<sup>3</sup> of 0.0M [[sugar]] [[solution]].#|}{| class="wikitable"|-|[[File:OsmosisPractical4.png|center|200px]]|[[File:OsmosisPractical5.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |:5.

Remove the pieces of plant tissue, drying them with a paper towel and measure their [[mass]].#|} :7. Plot a graph showing the concentration of [[sugar]] [[solution]] on the x-axis and the change in [[mass]] of plant tissue on the y-axis.
