Question

(Please explain the answer. Thank you!)

Answer 1

Sample cost = $15.796

Further explanation

Given

Mass = 2 g

Density = 0.718 g/ml

Cost =  $5.67 per mL

Required

Cost

Solution

The density : the ratio of mass and volume

Can be formulated :

Density (ρ) = m : V

The volume of the liquid :

V = m : ρ

V = 2 g : 0.718 g/ml

V = 2.786 ml

Sample cost :

= 2.786 ml x $5.67/ml

= $15.796
