Answer:
I think it would be at 0.7 kg mass of the sun
The answer is 3). This is because elements are the simplest form of a substance, and cannot be broken down any further. Compounds on the other hand are much more complex than elements and can be broken down INTO elements.
For example, Na, sodium, is an element and cannot be broken down further. H2O, water, is a compound and can be broken down into Hydrogen and Oxygen.

The number of molecules of water is calculated as follows
find the moles of water= moles=mass/molar mass
moles = 69.1g/18 g/mol = 3.84 moles
by use of Avogadro law constant
that is 1 mole = 6.02 x10^23 molecules what about 3.84 moles of water
the molecules of water = (3.84 x 6.02 x10^23) = 2.312 x10^24 molecules
