solution:
1000 = m*2400*(78-22) + m*8.79*10^5
1000= 134400m + 879000m
1000= 1030200m
m = 1000/1013400
m= 1013.4 grams
the final answer is 0.9706 grams
No more solute will dissolve at that temperature, the temperature would have to be increased in order for more solute to dissolve.
Heat is energy, and that energy would eventually cause the object to undergo a phase change.
