Te answer is 2moles because 72/36 is 2

The answer is 2 moles
Number of moles = mass/molar mass
That gives us 72g/36g = 2.0 moles

check: water is the solvent and the question wants amt of salt x in 100g of H2O ...
at 343k =72g
we have : 72/100 = 0.72g.

0.7g is correct.

Solubility = 1moldm-³
Volume = 700g
[Since it's per 100 according to the graph and it relates to the 70(approx) point of X.

Using
M = m/mm × 1000/volume
1 = ## × 1000/700

## = 0.7//
