A certain liquid has a density of 2.67 g/cm³. 30.5 mL of this liquid would have a mass of __________ Kg. A) 0.0114 B) 81.4 C) 11.4 D) 0.0814 E) 0.0875

Question

Quizplus · Accepted Answer

Density = mass/volume 
Rearranging the equation, mass = density x volume

Given density = 2.67 g/cm³ 
Volume = 30.5 mL = 30.5/1000 = 0.0305 cm³

Substituting the values, 
Mass = 2.67 x 0.0305 
Mass = 0.0814 g

Converting grams to kilograms, 
Mass = 0.0814/1000 
Mass = 0.0000814 kg

Therefore, the mass of 30.5 mL of the liquid is 0.0000814 kg or 0.0814 g, which is closest to option D.
