The diagram shown above represents the solubility curves of two salts, X and Y, in water, use this diagram to answer the question. If the molar mass of X is 36 g, the number of moles of X dissolved at 343 K is
A.
0.2 moles
B.
0.7 moles
C.
1.5 moles
D.
2.0 moles
E.
3.0 moles
Correct answer is D
The molar mass of x = 36g. At 343k, 72g of x dissolved
Molarity of x = \(\frac{72}{36}\) = 2.00moles.
