A comprehensive guide explaining how to calculate percentage change in mass and conducting an osmosis experiment with potato in sugar solution to demonstrate the effect of water concentration on potato osmosis.
- The percentage change calculation involves finding the difference between final and initial mass, dividing by initial mass, and multiplying by 100
- The osmosis experiment uses potato discs in various solution concentrations to observe mass changes
- Mass changes indicate water movement through osmosis, with increases showing water absorption and decreases showing water loss
- The solution concentration where least mass change occurs matches the potato's water concentration
- Results help understand how osmosis affects cell mass in different environments
