Please answer as fast as possible

Answer 1

1. density of liquid: 1 g/cm³

2. density of unknown liquid: 2.7 g/cm³

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:

`\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}`

ρ = density

m = mass

v = volume

`\tt (156-56)/(100)=1~g/cm^3`

2.
`\tt (27)/(((30-20)/(1)) )=2.7~g/cm^3`
