Question

The density of liquid mercury is 13.6 g/mL. What is its density in units of lb/in​3​? (2.5 cm+1 in., 2.205 lbs= 1 kg., 1000 g =1 kg, 1 mL = 1 cm3).

Answer 1

Density,
`\rho=0.49\ lb/in^3`

Step-by-step explanation:

It is given that the density of liquid mercury is 13.6 g/mL. We need to convert the density into lb/in³.

We know that,

2.205 lbs= 1 kg

1 g = 0.0022 lb

1 mL = 0.0610 in³

`13.6\ (g)/(mL)=13.6* (0.0022\ lb)/(0.0610\ in^3)\\\\=0.49\ lb/in^3`

So, the density of liquid mercury is
`0.49\ lb/in^3`.
