Answer 1

Moles of Hg = 11.9

Further explanation

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

`\tt \rho=(m)/(V)`

ρ = density

m = mass

V = volume

• mass of Hg

Density = 13.55 g/ml

volume = 176 ml

`\tt mass=volume* density\\\\mass=176* 13.55=2384.8~g`

• mol of Hg

`\tt mol=(mass)/(Ar)\\\\mol=(2384.8)/(200.59)=11.88\approx 11.9`
