look at this graph. If the slope of platinum is 8g/cm3, and the y int is 0, predict the mass at 15cm3.
set up y=mx +b
substitute 8 for m, 15 for x, 0 for b. solve.
120g

1)Look at this graph, what is the slope of lead? 2)What is the density??
Lead= 11.4g/cm3
The slope IS the density!!

How do you find the volume of a solid? Liquid? Irregular solid?
solid- l x w x h
liquid - graduated cylinder
irregular solid- Water displacement
500
If an objects density is 1.3g/ml will it sink or float in water. WHY?
Sink because it is more dense than water which has a density of 1g/ml

What is the density of a watch if it weights 200g and if I dropped it in a graduated cylinder, the water went from 45 to 100ml?
D= m/v
200g/55ml = 3.6g/ml
