Question

QUESTION IS DOWN BELOW 15 POINTS EACH

Answer 1

a) d = 2.5g/cm3

b) m = 1690g

Explanation:

density equals mass between volume

a)
`d=320g/128cm^(3) =2.5g/cm^(3)`

mass equals density by volumen

b)
`m=(26g/cm^(3) )(65cm^(3) )=1690g`

Hope this helps

Answer 2

a)

density = mass/volume

density = 320/128

density = 2.5 g/cm3

b)

mass = density x volume

mass = 65 x 26

mass = 1690g
