Question

lenny accidentally drops his matchbox car into a graduated cylinder. if the car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. determine the density of the matchbox car. the formula for density is d = m v

Answer 1

2.0

Step-by-step explanation:

Answer 2

Answer: Denisty = 2.0 g/mL

`Density =(Mass)/(volume)`

The mass of the matchbox is,
`m = 10 g`

The volume of the cylinder = volume of water displaced in the cylinder when matchbox is immersed = final volume - initial volume.

`V=v_f-v_i=46 mL-41 mL=5.0 mL`

`Density =(Mass)/(volume)=(10g)/(5mL)=2.0g/mL`

Hence, the density of matchbox is 2.0 g/mL
