The mass of a block is 12 g and the volume is 6 ml. Calculate the density of the block.
HACTEHA [7]

Answer:

According to mass and volume,  block density is 2 g/ml

Explanation:

Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.

In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.

The formula used to calculate the density is

ρ = \frac{m}{V}

Therefore, according to the mass and density of the block

ρ = \frac{12}{6} = 2g/ml

Being the density of the block equal to 2 g/ml.

<em>The other options are not possible, because the values given do not correspond to the result of the equation.</em>

At constant temperature,

PV = Constant

so,

P1.V1 = P2. V2

101 × 2.1 = 235 × V2

V2 = 0.9 L
