Question

Physics question?

A large tanker truck can carry 21 tons (42,000 lb) of liquid.

(a)
What volume of antifreeze (in ft^3) can it carry?

_____ f^t3

(b)
What volume of pure water (in ft^3) can it carry?

_____ ft^3

Answer 1

We using the equation of the density
ρ=m/V
Therefore, we get volume
V=m/ρ
(a) Antifreeze density is 69.3 lb/ft3
V=(42000 lb)/(69.3 lb/〖ft〗^3 )
V=606 〖ft〗^3 antifreeze
b) Pure water density is 69.3 lb/ft3
V=(42000 lb)/(62.2 lb/〖ft〗^3 )
V=675 〖ft〗^3 pure water
