0.2 moles
0.7 moles
1.5 moles
2.0 moles
3.0 moles
Correct answer is D
The molar mass of x = 36g. At 343k, 72g of x dissolved
Molarity of x = 7236 = 2.00moles.
only 10g of X undissolved
only 16 g of Y undissolved
10 g of X and 16 g of Y undissolved
all X and Y dissolved
all X and Y undissolved
Correct answer is B
For salt X, from the graph, 80g of X dissolves by 349K, so by 353K, all 80g of X is dissolved totally in 100g of water. For salt Y, from the graph, 64g of Y dissolves by 353K, so (80-64)g of Y is left undissolved. This is 16g of Y left undissolved at that temperature.
Y is twice as soluble as X
X is twice as soluble as Y
X and Y are soluble to the same extent
X is three times as soluble as Y
Y is three times as soluble as X
Correct answer is A
