How many total atoms are in 0.250g of p2o5?

Explanation:

According to the mole concept, there are atoms present.

It is given that mass is 0.250 g. And, number of moles are equal to mass divided by molar mass.

Mathematically,       No. of moles =

As molar mass of is 283.88 g/mol. Therefore, putting given values into the above formula as follows.

                 No. of moles =

                                       =

                                       = 0.0008 mol

Hence, number of atoms present in 0.0008 mol are as follows.

                     = 0.0048 atoms

Thus, we can conclude that there are 0.0048 atoms in 0.250 g of .
