Question

The density of aluminum is 2.70 g/cm². Express this value in terms of g/L and kg/in³.

A) 2.70g/L and 0.164kg/in
B) 2.70g/L and 2700kg/in
C) 0.0027g/L and 2700kg/in
D) 0.0027g/L and 0.164kg/in

Answer 1

The density of aluminum in terms of g/L is 2700 g/L and in terms of kg/in³ is 0.164 kg/in³.

Step-by-step explanation:

The density of aluminum can be expressed in terms of g/L and kg/in³. To convert from g/cm³ to g/L, we need to multiply the density by 1000, since there are 1000 cm³ in 1 L. So, the density of aluminum in g/L is 2.70 g/cm³ x 1000 = 2700 g/L. To convert from g/cm³ to kg/in³, we need to multiply the density by a conversion factor. 1 kg/cm³ is equal to 0.0610237 lb/in³, so the density of aluminum in kg/in³ is 2.70 g/cm³ x 0.0610237 kg/in³ = 0.164 kg/in³.
