Calculate the molecular mass of tetraphosphorus decaoxide, p4o10, a corrosive substance which can be used as a drying agent.

The molecular mass is the mass of all the atoms present in the molecule. The molecular mass of the compound is calculated using the steps:

1. Determine the atomic number of each element in the compound.

2. Each element's atomic mass is multiplied by the number of atoms in that element in the compound.

3. The mass of all the atoms are added up.

The given compound is:

The atomic mass of

The atomic mass of

The molecular mass of =

The molecular mass of = =

Hence, the molecular mass of is .

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
