Aluminum has a density of 2.70 g/cm3.

What would be the mass of a sample whose volume is 10.0 cm3?

 

---------------------------------------------------

 

밀도 = 질량 / 부피 이므로,

( 참고 https://ywpop.tistory.com/8460 )

 

질량 = 밀도 × 부피

= (2.70 g/cm3) × (10.0 cm3)

= 27.0 g

What would be the mass of a sample whose volume is 50.0 cm3?

 

질량 = 밀도 × 부피

= (2.70 g/cm3) × (50.0 cm3)

= 135 g
