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>

<u>Answer</u>:

Electric evaporator has been used to clean up the Chernobyl and 3 mile island accident.

<u>Explanation</u>:

About 14 years back, there was a puff of radioactive steam from the evaporator used in the "Three-mile island" nuclear plant. It took two years for the electric evaporator to clean up the 2.2 million gallons of water that have been destroyed because of the nuclear power plant accident.

The steam that came out of the electric evaporator carried a radioactive form of hydrogen and tritium with itself. Cost of clean up was $1 billion.
