If the mass of a material is 12 grams and the volume of the material is 49 cm^3 , what would the density of the material be?

4.0 g/cm^3
4.08 g/cm^3
.24 g/cm^3
none of the above

Density = 0.24 g/cm3

Explanation:

Given:

Mass of the material = 12 g

Volume of the material = 49 cm3

To determine:

The density of the material

Formula:

Density of a substance is the ratio of the mass of the substance present in the given volume

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
