Question

How many atoms and molecules of phosphorus are present in 124gm of phosphorus (p4)?

Answer 1

@UnkleRhaukus pleaz help:)

Answer 2

What is the molar mass of 'P' first of all?

Answer 3

And so, what would be the molar of a P4 atom containing 4 'P' atoms per molecule.

Answer 4

molar mass of P is 31, so p4 will be of 124 units.k! now

Answer 5

Answer 6

Now.124 g is the molar mass of P4 - that means one mole of P4 contains 124 g. Which is exactly the mass that has been provided to you as well - 124 g. So that should contains how many molecules? And how many atoms - considering that there are 4 atoms per molecule.

Answer 7

As an extra, do you know what the structure of P4 is like?

Answer 8

no! but I have got the answer thanx:)
