Iron has a density of 7.86 g/cm3 (1 cm3=1 ml). calculate the volume (in dl) of a piece of iron having a mass of 3.26 kg . note that the density is provided in different units of volume and mass than the desired units of volume (dl) and the given units of mass (kg). you will need to express the density in kg/dl (1 cm3 = 1 ml) before calculating the volume for the piece of iron.

Answer : The correct option is,

Explanation :

Diarsenic pentoxide having the formula, . It is a covalent compound which is formed by the sharing of electrons between the two non-metals. The two non-metals are arsenic (As) and oxygen (O).

When the two arsenic atoms share their electrons to the five oxygen atoms to form covalent compound.

The formula of covalent compound is given by :

The less electronegative element is written first.The more electronegative element is written second.If the prefixes are written with the elements then the prefix number is written in the subscript of the respective elements.

Hence, the formula for diarsenic pentoxide is,
