Volume V = length l × width w × height h
mass m = density ρ × Volume V
The first graph shows data gathered by a student in SC 130 physical science.
__________ _____ Calculate the density ρ of the soap (include units!).
______________ Will the soap floatorsink?
______________ Toughie: Based on the density and your experience in the laboratory, what brand of soap is this?
__________ _____ A student measures a bar of soap with a length of 7.9 cm, a width of 3.9 cm, and a height of 1.7 cm. What is the volume of the soap?
__________ _____ A student measures a bar of soap with a length of 7.9 cm, a width of 3.9 cm, and a height of 1.7 cm. The soap has a mass of 58.9 grams. What is the density of the soap?
___________ _____ A bar of soap is found to have a density of 1.3 g/cm³. If the volume of the soap is 50 cm³, what is the mass of the soap?
___________ _____ A lead cube is found to have a density of 11.4 g/cm³. If the mass of the cube is 365 grams, what is the volume of the cube?
For the data and chart shown calculate the following:
__________ _____ What is the density ρ of the soap?
__________ _____ What is the y-intercept for the soap?
