Final Jeopardy Question:An unknown substance has a
density of 7.87 g/cm3 and mass of 15.74 grams what is its volume?
Will it sink or float in water?
Show ALL WORK on white board
VOLUME = MASS / DENSITYVOLUME = 15.74 g / 7.87 g/cm3
VOLUME = 2 cm3
•SUBSTANCE WILL SINK IN WATER
Final Jeopardy Answer:
Final Jeopardy Question:
An unknown substance has a density of 0.85 g/cm3 and volume of
3.38 cm3 what is its mass?
Will it sink or float in water?
Show ALL WORK on white board
MASS = DENSITY x VOLUMEMASS= 0.85 g/cm3 x 3.38 cm3
MASS = 2.873 g
• SUBSTANCE WILL FLOAT IN WATER
