salt 0.547 g 5.70 mL oil 5.95 mL density g cm-3

 

 

A crystal of salt was grown and

found to have a mass of 0.547 g.

When the crystal was placed in a graduated cylinder

that contained 5.70 mL oil, the volume increased to 5.95 mL.

What is the density of salt?

Give your answer in g cm ^-3

since the density of solids are reported in g cm^-3.

메스실린더의 증가된 부피 = 염의 부피

( 아르키메데스의 원리 )

 

 

 

밀도 = 질량 / 부피

= 0.547 g / (5.95 – 5.70 cm^3)

= 2.19 g/cm^3

 

 

 

답: 2.19 g cm^-3
