2.
A key displaces 7 ml of water and has a mass of 59.5 grams. What is its density?
(how could you determine what is it made of??)
(how could you determine what is it made of??)
a)
D = M/V 59.5g/ 7ml = 8.5 g/ml

D = M V =7 x 59416.5 gml
3.
If you are given the density and volume of an item, how would you calculate its mass?
a)
D = M/V SO..
M = D/V

M = V/D
M = V/D
c)
D = M/V SO...
M = D x V
M = D x V
