> 1 qt (US) = 0.946352946 L (approximately)

( 참고 https://ywpop.tistory.com/17461 )

 

> 0.880 g/cm3 = 0.880 g/mL

 

 

 

(2.83 qt) (0.946352946 L / 1 qt) (1000 mL / 1 L) (0.880 g/mL)

= (2.83) (0.946352946) (1000) (0.880)

= 2357 g

 

 

 

답: 2.36×10^3 g

 

 

 

 

[참고] mass of 2.22 qt benzene

= (2.22) (0.946352946) (1000) (0.880) = 1.85×10^3 g

 

 

[참고] mass of 2.26 qt benzene

= (2.26) (0.946352946) (1000) (0.880) = 1.88×10^3 g
