Volume V = length l × width w × height h
mass m = density ρ × Volume V
The graph shows soap density data. Use the graphed data to answer the following questions.
__________ _____ Calculate the density ρ of Dial Basic soap.
______________ Based on the density, will Dial Basic soap floatorsink?
__________ _____ Using the density above, calculate the mass of a bar of Dial Basic soap that has a volume of 100 cm³.
__________ _____ Using the density above, calculate the volume of a bar of Dial Basic soap that has a mass of 250 grams.
__________ _____ Calculate the density ρ of Ivory soap.
______________ Based on the density, will Ivory soap floatorsink?
__________ _____ Calculate the density ρ of Neutrana soap.
______________ Critical thinking: Based on the density, will Neutrana soap floatorsink?
A student gathered the data seen in the table below.
Plot the soap data on the graph.
__________ __________ Calculate the density of the soap. Include the units with your answer.
______________ Based on the slope, will this soap [float]OR[sink]?
______________ Based on the slope, is this soap likely to be [Ivory]OR[Dial] soap?
__________ __________ Calculate the mass for this soap for a volume of 200 cm³.
__________ __________ Calculate the volume for this soap for a mass of 240 g.
Critical thinking: Some laboratory groups obtained slopes which incorrectly predicted whether their soap would float or sink. Which are they more likely to have measured incorrectly and WHY: the volume or the mass?
